Thank you for viewing. This is a very thin pouch made by knitting with 100% acrylic yarn, without a gusset or lining. The size is approximately 12 cm in height and 18 cm in width, and about 19 cm when opened. It can hold masks, point cards, etc. As this is a handmade item, please understand that there may be some distortion in the shape, slight differences in size, and the color may differ slightly from the photos. Thank you for your understanding.
