Durable laminated fabric abacus case for 23-digit abacuses. Can be changed to accommodate 27-digit abacuses. 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: Approximately 36cm long x 10cm wide To make it easier to take out, the abacus extends about 2cm from the bag. The closure is 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 differ from the image. Please be aware of this. *Can be changed to 27-digit size (27-digit size: Approximately 42cm long x 10cm wide). Also, you can add a loop to hang it on a school bag or a desk hook (see the third photo). Please contact us before purchasing. If you purchase without contacting us for changes, we will send you the 23-digit version without a loop. Please note that we will not exchange it after shipping. ☆Many other patterns are also available. We make each item with care, but as these are handmade by amateurs, there may be slight imperfections in the stitching or alignment. Please refrain from purchasing if you are looking for perfection. We appreciate your understanding. #AbacusCase #ElementarySchoolStudent #Abacus
