High-quality dye, black. Suitable for various materials. - Brand: Colordye All - Color: Black Thank you for viewing. I bought this dye with enthusiasm, but it became too much trouble, and I've been storing it at home. It was new and unopened, but I have now opened it to check the item. The dye powder is in good condition, but please be aware that approximately 10 years have passed since its purchase. An instruction manual is included, but the content volume is not listed. The weight including the container is 27g. I believe the content volume is probably around 20g. (According to Amazon, it is sold in 20g packages) Please consider the condition carefully, and if you are concerned about the details, please refrain from purchasing. Thank you.
