Durable laminated fabric abacus case for 23-digit abacuses. Can be changed to 27-digit size. Thinner than commercially available products. The material is cotton with a vinyl coating, so it won't get wet inside in light rain. Size: For 23-digit abacus: Length approx. 36cm x Width 10cm To make it easier to take out, the end of the abacus sticks out of the bag by about 2cm. The opening and closing uses Velcro, which is easy for small children to open and close, as snaps can be difficult to use and may hit the beads. *Because we cut in bulk, the pattern may appear differently from the image. Please understand. Immediate purchase is OK. However, if you have any of the following changes, please contact us before or immediately after purchase. *Can be changed to 27-digit size (for 27-digit abacus: Length approx. 42cm x Width 10cm). Also, you can add a loop to hang it on a school bag or a desk hook. (See the 3rd photo for reference) Please contact us before purchasing. If you purchase without contacting us about the changes, we will send you the 23-digit size without a loop. Please note that we will not exchange it after shipping. We carefully finish each item with care, but as these are handmade by amateurs, there may be some slight unevenness or misalignment in the stitching. Please refrain from purchasing if you are looking for perfection. We appreciate your understanding before purchasing. Pattern/Design: Check #AbacusCase #Handmade #ElementarySchoolStudents
