Thank you for viewing my listing.
This is a high-quality watercolor paper block with 20 sheets. I was looking for the best paper for colored pencil drawings and saw a famous international YouTuber using this paper, so I bought it to try. I used one sheet and have kept the rest.
Since I don't think I'll have another opportunity to use it, I'm putting it up for sale.
There is a small gray mark, about 3mm, on the edge of the first sheet of paper (see image 3). I cut the paper from the block before using it, so I don't think it damaged the sheets underneath. I'm unsure if it was there originally or if a colored pencil accidentally touched it.
The other sheets underneath are glued on the sides and cannot be separated, so they are undamaged.
Please refrain from purchasing if you are concerned about minor details.

Below is the product description.
Thank you for your consideration.
