The Storex Large Craft Organizer Tray is built using a high-impact polypropylene formulation, offering a balance between lightweight handling and chemical resistance. This material choice ensures the trays remain unaffected by most craft solvents and adhesives. The design prioritizes nesting efficiency for easy storage when the trays are empty, featuring an integrated rim lip that allows the units to sit together securely on a flat surface.
Specifications indicate a wall thickness of approximately 1.4mm to 1.8mm. While this makes the trays easy to carry, tests show that loading the units beyond 4.5kg can lead to visible base sagging. To maintain the structural integrity of the stack, it is most effective to use these for lighter items such as paper, stationery, or basic craft kits. Because the stacking mechanism relies on gravity rather than a locking detent, the trays perform best when placed on perfectly level surfaces to prevent sliding.
Usability and Practical Limits
The footprint of these trays is specifically optimized for standard 12-inch office or classroom shelving depths. The high pigment saturation of the plastic helps mask internal stress marks that can occur with frequent use, keeping the organizers looking clean over time. However, the smooth interior surface may make very fine items, like needles or tiny beads, slightly more difficult to pick up compared to textured bins.
For those who need to organize a wider variety of smaller components in a single set, the 21-Pack Colorful Organizer Trays provide more modular pieces for detailed sorting. You can find these and other versatile storage solutions in our activity tray organizers category.
