Pink paper, B4 size, 60 sheets. I purchased this quite a while ago and have kept it stored in its original bag, so it appears to be free of discoloration. The thickness is unknown. The photos were taken indoors on a sunny day. I feel like the actual color is a bit brighter. I'm not confident in my description of the color or my photography, so if you're okay with "it's pink!" then perhaps this is for you. Please understand that this is a used item that has been stored at home for a long time before purchasing. Thank you for looking.
