I've had this stored away since I bought it. It's unused, but please refrain from purchasing if you are concerned. Although it's new and unused, it has been stored for a long time in a private home, so deterioration over time is possible. Please refrain from purchasing if you are sensitive to this. Material is unknown. Size is approximately 45cm square. Measurements are approximate due to amateur measuring. This is a cushion cover, but it's also recommended for use as a remake material. Tote bags, eco-bags, shopping bags, lunch wraps, and more. I hope you can use it creatively. It will be folded and placed in an envelope. It will be placed in the envelope as is, as putting it in film will cause it to expand and increase the thickness. ☆For shipping via standard mail, non-standard mail, Click Post, or Letter Pack☆ I will determine the shipping method after packaging and weighing the item. The cheapest shipping method will be used. Therefore, if it is sent via non-standard mail, Click Post, or Letter Pack, there is no insurance. Click Post and Letter Pack only offer tracking, and there is no insurance. I am not responsible for any accidents, damage, soiling, breakage, non-delivery, or incorrect delivery during transit, so please only purchase if you understand and accept this. I will not be able to investigate or handle any issues that may arise.
