This bag can also be used as a laundry hamper by leaving it open. Therefore, there is no need to "transfer" your laundry to your washing machine or hamper. Moreover, the round, shape resistant material of the bag will not hold up to the movement of the washing machine and prevent clothes from getting tangled. We also pay attention to the zipper. In addition to the sewing technology unique to bag makers, the zipper pulls have a looped string. The zipper pull is smooth enough for even small children with weak strength to grab the string to open and close.
