II. Core Selling Points

1. Thickened aluminum-magnesium alloy frame with metal corner guards for superior drop resistance, wear resistance and deformation prevention: The entire case is edged with thickened aerospace-grade aluminum-magnesium alloy profiles, and integrated stamped metal anti-collision corner guards are fitted on four corners. They cushion and disperse impact force during drops, knocks and squeezes, effectively resisting dents, cracks and deformation. The matte wear-resistant panel repels fingerprints, cosmetic pigments and workshop grease, and can be wiped clean effortlessly.
2. Dual metal safety latches with lock holes for anti-theft, sealed and splash-proof performance: Two sets of thickened metal spring latches are mounted on the front of the case, and each lock cylinder is equipped with a brass anti-theft lock hole where small padlocks can be attached to store high-value cosmetics and precision instruments. When the latches are closed, they compress the sealing rubber strip to block splashes of daily rainwater, dust and cosmetic mist, preventing internal equipment from rusting and dust accumulation.
3. Built-in metal support hinges keep the lid open stably without bouncing back: Thickened metal support brackets are installed on both sides. Once the lid is opened, it automatically locks at a 90-degree angle without manual holding, freeing your hands for makeup touch-ups and equipment maintenance and facilitating access to tools and cosmetic supplies. The rust-proof and wear-resistant metal brackets remain tight and deformation-free after tens of thousands of opening and closing cycles.
4. Central non-slip soft rubber handle for lightweight single-hand carrying: The integrated embedded non-slip soft rubber grip fits the curve of your palm, causing no discomfort even when carrying the fully loaded case for extended periods. Weighing merely 1.85KG, the compact case can fit into backpacks and the passenger seat of cars, eliminating carrying burdens during short commutes and on-site visits.
5. Two optional storage solutions to flexibly meet diverse usage needs: The basic version features an empty inner compartment plus an Oxford cloth storage pouch on the lid for separate storage of brushes, wires and small accessories. The upgraded version offers optional high-density wave-shaped shock-absorbing foam that can be freely cut to form custom slots, protecting lenses, precision detectors and nail art drills from scratches. Custom integrated EVA foam liners are also available to fix multiple small devices in separate independent compartments.
6. Weather-resistant composite panel resists aging and cracking under extreme temperatures: Combined with aluminum-magnesium alloy borders, the frosted ABS composite panel will not turn white or become brittle under intense sunlight exposure inside cars in summer or low-temperature outdoor conditions in winter. It withstands corrosion from cosmetic alcohol and mild industrial cleaners, delivering enhanced durability for long-term outdoor use.
7. All-scenario lightweight portable design with full customization support: Boasting a matte black business-style appearance, the flat front surface of the case reserves an area for logo engraving, enabling laser engraving and screen printing of store brands and enterprise serial numbers. Bulk orders support customized color schemes, adjusted inner liners and modified case dimensions to cater to exclusive storage demands across beauty, instrument and maintenance industries.

1. Dual Sets of Anti-Theft Metal Spring Latches

Symmetric thickened metal latches are fitted on the front of the case, with built-in brass keyholes for padlock installation. They prevent cosmetics and precision instruments from being lost during external storage or long-distance transport. The latches deliver consistent spring tension and will not pop open automatically on bumpy roads. When closed, they compress the sealing strip to enhance dustproof and waterproof performance.

2. Double-sided Metal Lid Support Brackets

High-strength rust-proof metal support rods automatically lock the lid at a 90-degree angle when opened, freeing both hands for makeup application and maintenance without holding the lid manually. The brackets are firmly riveted and will not loosen or fall off after frequent opening and closing.

3. Oxford Fabric Storage Pouch on Case Lid

Thickened waterproof Oxford fabric pockets are sewn onto the case lid, which can hold makeup brushes, wires, manuals and small accessories. Items can be stored separately without tangling, making them easy to find at a glance.

4. Thickened Metal Anti-Collision Corner Guards at Four Corners

Integrally stamped metal corner wraps are fitted on all four corners of the case to fully enclose the edges. They prevent the case corners from scratches and deformation during drops, collisions, stacking and squeezing, thus extending the service life of the case.

IX.FAQ

Q1: What items are suitable for storage in this small aluminum case, and what precautions should be taken when carrying it fully loaded?

A: It fits complete makeup and microblading tool sets, small precision testing instruments, mini repair tools, drone accessories and small digital devices. When moving the fully loaded case, support the bottom of the case with both hands to prevent slight deformation of the aluminum frame caused by concentrated pressure on a single side corner.

Q2: Can metal latches and support brackets be replaced with separate spare parts if damaged?

A: All hardware accessories are standard universal parts. Contact customer service and provide your case model number, and separate latches and brackets can be sent for self-replacement.

Q3: How waterproof is the case, and can it be washed directly with water?

A: The case only provides daily splash-proof and dust-proof performance. It must not be soaked for long periods or sprayed directly with high-pressure water guns. Wipe dirty surfaces with a damp cloth to prevent water seepage inside and damage to stored equipment.

Q4: How can I tell if my instrument or makeup palette will fit inside the case?

A: Measure the overall length, width and height of your equipment. It can be fully placed if its dimensions are smaller than the inner compartment size of 380×217×130mm. If your items are oversized, consult customer service for larger-size aluminum protective cases.

Q5: Will the aluminum frame and plastic handle crack easily when used outdoors in low winter temperatures?

A: The aluminum-magnesium alloy maintains stable toughness under low temperatures, and the ABS panels are blended with cold-resistant modifiers, so they are not prone to brittle cracking under normal sub-zero outdoor conditions. Open and close the latches gently in cold weather to reduce hardware wear.

Q6: What is the minimum order quantity for custom integrated EVA liners, and can they store multiple sets of small tools in separate compartments?

A: The minimum order quantity for custom molded liners is 300 pieces. Independent grooves can be molded for makeup brushes, instrument probes and repair tools at the same time for neat layered and zoned storage.

Q7: How should I clean and maintain the case if it gets stained with cosmetic pigments or machine oil?

A: Wipe the panels and gaps of the aluminum frame with a soft cloth and neutral detergent. Dry all metal hardware thoroughly to avoid oxidation from water stains. Store the case only after it is completely dry to prevent long-term residual stains from corroding the frame.
