Soft and durable It is a gray felt material. I think you can use it for various purposes such as cushioning material, soundproofing, and vibration proofing. The thickness is about 6-8mm. The size is about 250mm x about 800mm, an easy-to-use large size. There are variations in size. It will be folded and tied for shipping. It's soft, so I don't think it will crease easily. It can be cut with scissors. Taking advantage of its soundproofing and sound absorption properties, it is used for car deadening and cushioning materials. It is relatively tightly packed, and I think it is suitable for deadening. If you need other sizes or a large number, please let us know in the comments section. * Due to the nature of the material, it is easy to fluff and fibers may come out. Please purchase after understanding the condition. Thank you for viewing. Thick gray felt, size 25cm x 80cm, thickness 6-8mm, perfect for deadening
