This is merchandise sold at the NCT DREAM cafe held in 2022. It has a gusset of about 4cm, making it quite spacious for a pouch. For reference, I used to put a few trading cards, a battery case, and acrylic stands in it when I went to concerts. The inside is a little dirty, but the outside is clean and can be used without any problems. If you have any questions, please comment ꕤ︎︎·͜· ︎︎
