Thank you for viewing. This is a set of 4 packs of 5 balls each of Foral + 4PLY yarn from Keito Zakka Stores, for a total of 20 balls. In the first photo, it looks black, but it's a dark brown. The color in the third photo is closer to the actual color. There are 20 balls (800g) in total, so I think you can knit a large project. These are new and unused, but they have been stored at a private residence, so we appreciate your understanding. Please note that we are not considering selling individual balls separately.
