※ The multi-colored yarn used here will be discontinued once my current supply runs out. Suitable for elementary school use! Knitted with 100% acrylic yarn. Please refer to the photos for size details. Rubber bands are knitted into the upper and middle sections for non-slip grip. The rubber bands are newly purchased. Please understand that the wear and tear will vary depending on the usage environment and the type of chair, and that they are consumable items. They are stretchy. If they become loose during use, try washing them in a net. For reference, there are no smokers or pets in my home. Shipping methods will be selected at my discretion, including standard (outside) mail and smart letter. Please note that tracking is not available after shipping, and I cannot be held responsible for any issues after the item has been delivered. I create these items with care, but they are handmade. I try to knit with consistent tension, but please understand that there may be slight variations. Please ask any questions before bidding to avoid any issues. Please read my profile. I am sorry, but I cannot offer a combined discount on this item due to the labor involved. m(__)m
