These are Ezo abalone shells. They come in various sizes, with most being small. Please check the images for size reference. The attached substances were removed by soaking in chlorine, then in fresh water, followed by sun-drying, and then removing the remaining attachments. How about using them for crafts or fishing tackle? Regarding the condition, I removed the attachments as much as possible while preserving the abalone itself. However, as these are natural shells, there may still be some remaining attachments, scratches, holes, etc. Please judge from the images for details. As these are handmade items, please examine the images carefully and we await orders from those who understand. Also, to prevent any issues, please refrain from ordering a specific number of items.
