This 10-pack of colorful activity trays is designed for light-duty sorting and child-led cleanup. Constructed from polypropylene homopolymer, these units are naturally resistant to acids and school-grade adhesives. The lightweight 1.4mm wall thickness makes them very easy for children to carry and maneuver, supporting independence in a classroom or playroom setting. The variety of high-contrast colors is particularly helpful for implementing sorting systems or Montessori-style "loose parts" play.
The trays feature a low-profile stacking lug, though they perform best when kept dry and free of oils to prevent sliding. While the material is dishwasher safe on the top rack, air-drying is recommended to avoid the warping that can occur during high-heat cycles. Users should be aware that under heavy loads—such as large volumes of wet clay or sand—the floor of the tray may exhibit flex. This unit is most effective when used for dry crafts, paper projects, or light manipulative toys.
The dimensions of 10x13 inches provide ample space for most standard craft activities. Because the polymer can become brittle in very cold environments, it is best to store these in climate-controlled indoor spaces rather than unheated garages. If your needs require a sturdier tray for "messy play" or heavy liquid loads, the Jmusttbo 5-Pack features a thicker 1.8mm base for improved stability.
