This is a set of a lunch box and a pouch. The pouch is cylindrical with an inner diameter of 9 cm. The lunch box does not have a warming function. Caution ⚠️ Although listed as a set, this lunch box does not fit in the pouch! I took it out of the box to take pictures, but it is brand new and unused. The pouch is also the same. The outer box has some folds and minor tears. As it has been stored at home, please refrain from purchasing if you are concerned about minor details. ★ Depending on the situation, the shipping method may be changed (from YuYu Mercari便 to RakuRaku Mercari便). Thank you for looking.
