The mammoth yarn has stains. The light blue yarn has broken threads. The light green yarn has some discoloration. I will compress the items for shipping. This will flatten them, potentially causing wrinkles in the bands, etc. If you prefer shipping without compression, please comment before purchasing. It will cost an additional 300-500 yen. Please note that you cannot change the shipping method after purchase. I bought these to use myself, but I haven't had the opportunity, so I'm selling them. I do not have any pets. Please refrain from purchasing if you are concerned about storage at home. These items are stored by an amateur. I take care, but please understand. Shipping is generally only on weekdays. Thank you. Up to 2 sets of medium-fine yarn can be shipped together. If you purchase multiple items, the discount will be 200 yen for the shipping cost.
