Detachable seals and lid simplify cleaning.
Design and Build Quality
Each of the 4 compartments is individually sealed to prevent mess and leakage, and the entire set is made from food grade materials that are BPA free. The 8 ounce thermo uses food grade 304 stainless steel with double wall vacuum insulation, keeping food warm or cold for up to 5 hours, and includes a built-in stainless steel spork for eating on the go.
The rubber sealing ring on the lunch box and the thermo's lid are both detachable for thorough cleaning.
Performance in Everyday Use
MAXSO states the set is 100 percent leakproof thanks to the individually sealed compartments, preventing both mess and smell-mixing between foods. The wide mouth thermo container is designed to be easy to clean by hand or in the dishwasher.
MAXSO recommends preheating or precooling the thermo with hot or icy water for 5 to 10 minutes before adding food or soup, to help the insulated container hold temperature longer.
