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 abacus extends about 2cm from the bag. The closure is Velcro, which is easy to open and close even for small children, as snaps can be difficult to use and may hit the beads. *Because we cut in bulk, the pattern may differ from the image. Please be aware of this. *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 hook on a desk. (See the 3rd reference photo) Please contact us before purchasing. If you purchase without contacting us for changes, we will send the 23-digit case without a loop. Please note that we will not exchange it after shipping. ☆We have many other patterns on sale. We carefully finish each item with care, but as they 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. #AbacusCase #Laminate #Kids #ElementarySchoolStudent
