Graded Card Storage Trolley Case

🧰 Super Large Capacity & Scientific Partitioning
The interior is meticulously designed to hold up to 50 standard-sized PSA slabs (exact number depends on slab thickness). Multi-layer compartments lined with high-density EVA give each slab its own dedicated slot, preventing collisions and scratches. A side mesh bag provides convenient storage for desiccants, labels, or small tools. Say goodbye to scattered stacking – transport entire batches at once.

🔩 All-Metal Body – Red & Silver Finish
Crafted from 1.2mm thickened cold-rolled steel plate with an electrostatic spray coating. The vibrant fire-engine red body, paired with matte silver pull rods and corner guards, strikes a perfect balance between professionalism and energy. The metal construction is pressure‑resistant, shockproof, and corrosion‑resistant, while effectively isolating external impacts, temperature, and humidity fluctuations – offering physical‑level protection for PSA slabs. Tested to withstand a static pressure of 200 kg.

🧳 Trolley Case Design – Move as Fast as Flying
Hidden three‑stage telescopic aluminum alloy pull rod ensures smooth, jam‑free operation. Double‑row universal silent casters (two with brakes) on the bottom glide effortlessly across laboratory floors, factory concrete, or outdoor surfaces. Ergonomic handles on both the top and side allow easy short‑distance carrying. The overall dimensions comply with carry‑on luggage specifications (verified with airlines), making it ideal for business trips.

🔒 Double Safety Locks
Equipped with two stainless steel combination locks (TSA‑certified optional) to prevent accidental opening during transport while still allowing security checks. Each lock features an additional handle for easy opening and closing – even with gloves on.

🌬️ Sealed Yet Breathable Balance
The inner side of the lid integrates a replaceable activated carbon filter (optional) that reduces moisture buildup and absorbs trace volatile substances, protecting PSA slab surfaces from contamination. Rubber sealing strips around the hinges provide IP54 dust and splash resistance.
