Available in 3 sizes to choose from according to capacity and purpose, making it easy to organize your suitcase. It's useful for business trips and travel, as well as for bag-in-bags, diaper pouches, and sorting children's clothes. Purchased new on December 15, 2025. Purchased for a trip abroad on the 18th.
