Tiger’s MCL vacuum insulated food jars are designed to keep food and beverages hot or cold for over 6 hours. This compact model comes in handy for meal preparation in the morning which can then be carried anywhere in any lunch box or bag without the inconvenience of spillage or the worry of diminished taste. The vacuum insulation technology used in Tiger’s select ranges creates a vacuum in between the double layers that form the jar during production. This vacuum prevents any heat transferring through it, making the contents of the jar invincible to external temperature conditions, thus achieving heat retention that can last up to 6 hours. The interior of the jars is polished to produce a super clean coating to make the inner surface resilient against stains and odors. The wide mouth and easily disassembled lid makes the food jars of this model easy to clean by hand. •Stainless steel material •Vacuum insulated double walled •2.8 inch wide mouth cup with round bottom for easy to scoop and eat •BPA Free
