Lightweight Full-Wrap Aluminum-Magnesium Alloy Frame with Metal Corner Guards, Compact, Drop-Resistant and Deformation-Proof: The entire case features a slim full surround frame made of aerospace-grade aluminum-magnesium alloy, with mini metal anti-collision corner caps fully covering all four corners of the case. It disperses impact force during drops, squeezes and bumps to prevent dents and bending of the compact case body. The matte frosted panel resists fingerprints, pigment stains and oil contamination, which can be effortlessly wiped off with a damp cloth, leaving no stubborn marks during outdoor carry.
Single Anti-Theft Latch with Brass Lock Cylinder, Sealed Against Dust and Splashes: A single thickened metal latch on the front is equipped with an embedded brass anti-theft lock hole, allowing users to attach a small padlock for storing valuable RC model parts and precision small inspection components. When fastened, the latch compresses the full-circle rubber sealing strip to block outdoor rainwater, dust and cosmetic mist, protecting internal small items from rust and dust buildup.
Multiple Optional Inner Liners for Flexible Storage of Various Small Items: ① Flocked Empty Liner: Spacious and minimalist, for flexible storage of small accessories of varying lengths; ② Three-Compartment Divider Liner: Removable partition boards to separately store RC propellers, screws and nail art tools; ③ Lid Mesh Pocket Liner: Mesh pouch for cables, manuals and tiny parts, with the lower compartment for larger accessories; ④ Wave-Shock Absorbing Foam Liner: Double-layer foam padding on top and bottom to cushion and safeguard lenses, sensors and precision components. Custom one-piece integrated EVA liners via mold opening are also available, with individual cutouts milled to match the shapes of small items for tidy, shift-free storage.
Integrated Anti-Slip Soft Rubber Handle, Ultra-Light for Hassle-Free Portability: A built-in short grip made of TPE anti-slip soft rubber conforms to finger curves, avoiding hand soreness even after long-time carrying with full contents. Weighing merely 1 kilogram, the compact case fits into backpacks and shoulder bags, ideal for RC flying sessions, on-site service trips and business travels.
Mini Compact Profile for Multi-Scenario Portable Storage: Its slim, miniature footprint saves space, suitable for desktop storage at home, outdoor carry and display of small sample products at exhibitions. The rigid aluminum shell delivers far superior protection compared to fabric pouches and plastic boxes.
Weather-Resistant Composite Panel with Full-Range Customization Services: Constructed with thickened ABS frosted composite panels paired with aluminum-magnesium frames, the case resists whitening and embrittlement under extreme high and low temperatures, as well as corrosion from alcohol and mild detergents. A flat reserved area on the front panel supports laser engraving and screen printing of RC shop logos, nail salon branding and corporate equipment serial numbers. Bulk orders allow customization of case colors, aluminum frame thickness and latch styles.

Single Anti-Theft Spring Latch with Brass Lock Cylinder
The thickened metal latch is mounted at the center of the case. Equipped with an internal brass lock hole, it allows installation of a mini anti-theft padlock to prevent loss of valuable drone model parts and precision small components during off-site storage or long-distance transport. The latch features firm elastic tension, so it will not pop open automatically when the bag jolts. It compresses the sealing strip to enhance dustproof and waterproof performance.
Multiple Optional Functional Liners
Three-Compartment Divider Version: Two detachable partition boards inside the storage compartment enable free division into three separate zones for sorted storage of screws, propellers and tools.
Lid Mesh Pocket Version: Multi-layer elastic mesh pouches store cables, manuals and small accessories, leaving the lower compartment with full intact space.
Wave Foam Version: High-density slow-rebound foam fully covers the top and bottom to clamp and secure precision small parts, providing scratch and impact resistance.
Mini Thickened Metal Anti-Corner Guards for Four Corners
Integrally stamped small metal corner wraps fully covering all four corners of the case deliver all-round edge protection. They shield the aluminum frames and panels from damage caused by dropping impacts and stacking pressure, preventing scratches and deformation even with long-term portable use.
Full-circle Embedded Sealing Strip
A complete rubber sealing strip is fitted along the joint of the case. When the latches are fastened, the strip closely fits the gaps to block dust and splashing water vapor from entering the case, providing long-term protection for small internal electronic components.
The standard matte black business version resists dirt and fingerprints, and oil stains as well as pigment smudges can be easily wiped off. Silver gray, champagne gold and army green case colors are available for customization on bulk orders.
Custom Logo Engraving: Laser engraving and screen printing of codes for model aircraft clubs, nail salons and electronic maintenance enterprises are supported on the flat area of the front case panel.

Q1: What items is this mini aluminum case suitable for storing, and what precautions should be taken when carrying it in a backpack?
A: It fits drone accessories, manicure small supplies, precision repair parts, earphone digital cables and mini testing instruments. When putting it into a backpack, avoid sharp and heavy objects squeezing the corners of the case to prevent slight deformation of the aluminum frame.
Q2: Can the metal latches and hinges be replaced separately if damaged?
A: The hardware parts are standard universal components. Contact customer service and provide the case model, and separate latches and hinges can be resent for self-replacement.
Q3: How water-resistant is the case, and can it be washed with water?
A: The case only offers daily splash-proof and dust-proof performance. It cannot be soaked for a long time or sprayed directly with a high-pressure water gun. Wipe the surface with a damp cloth when dirty, and dry it thoroughly before storing small items.
Q4: How to confirm whether accessories and small objects can fit inside the case?
A: Measure the overall length, width and height of the items. They can be fully placed inside if their dimensions are smaller than the inner compartment size of 303×213×113mm. For oversize items, consult customer service for larger-sized aluminum protective cases.
Q5: Are the aluminum frame and plastic handle prone to damage when used outdoors in low winter temperatures?
A: The aluminum-magnesium alloy maintains stable toughness under low temperatures, and the ABS panels are added with cold-resistant modifiers, so they will not crack easily under normal sub-zero outdoor conditions. Operate the latches gently when opening and closing in cold weather to reduce hardware wear.
Q6: What is the minimum order quantity for custom integrated EVA liners, and can separate grooves be made for different types of small items in different zones?
A: The minimum order quantity for liner mold opening is 300 pieces. Independent grooves can be made simultaneously for drone propellers, manicure tools and sensors to neatly store a full set of small items in separate layers and zones.
Q7: How to clean and maintain the case when it is stained with drone engine oil or manicure pigment?
A: Wipe the gaps of the aluminum frame and panels with a soft cloth and neutral detergent. Dry all metal hardware to prevent oxidation, and store items only after the case is completely dry to avoid long-term corrosion of the aluminum-magnesium frame by stains.
