Outer container size: 17.4 x 10.7 x 2.7 cm. The whole unit is transparent so you can quickly see what is stored inside. Detachable design: Each small box is separate from the others, so you can remove one and use it directly without affecting the rest. The 28 compartments in every box can be used individually or together as needed. High quality and reliable sealing: Made of durable plastic with sturdy construction. The lids provide reliable sealing and double lid sealing helps keep contents secure even with frequent opening and closing. The boxes resist deformation during daily use.

The 28 compartments per module make it easy to sort and access items, keeping spaces tidy. Use scenarios: - Craft and jewelry storage: separate beads, findings, and small components for easy access. - Small parts organization in workshops or garages: sort screws, nuts, bolts, and fasteners. - Sewing, crafting, and home organization: keep needles, threads, buttons, and small tools neatly arranged in the kitchen, bathroom, or wardrobe.
