At Klean Hygiene, we strive to make the highest quality products available to you. Our snack tray with lid is made from a combination of both PP and PET materials - making our snack trays food safe, BPA-free and highly durable! Each lid is made with a silicone barrier and snap-locks on each side, ensuring an airtight and spill resistant seal. This attention to detail makes these containers great for all things traveling and hiking, as well as picnics, parties or even cookouts! Our large container measures 11 inches x 8.3 inches x 2.6 inches and hold 8 dividers . Our small containers measure 8.3 inches x 5.5 inches x 2.6 inches and hold 4 dividers each. Each divider measures 4 inches x 2.7 inches x 2 inches. Friendly Reminder - When cleaning, high heat and pressure could cause warping. Due to this possibility, these containers are not dishwasher safe and must be hand washed.
