Approximately 24 x 20 cm. We've created a set of different patterns in the same size. I make them with care, but there may be some imperfections like slight distortions or uneven stitching. I haven't used edge stitching on the seams. Recommended for those who aren't good at sewing and don't mind these minor flaws, perfect for preparing for kindergarten or school. #RecommendedForThoseWhoAreNotGoodAtHandmadeKindergartenEntrancePreparationSet I also have lunch bags, chopstick and spoon cases, masks, and more for sale. Please note that the drawstring bags come in various sizes. If you'd like to purchase multiple items, please comment. I'll offer a small discount as a token of appreciation.
