Thank you for viewing. Survey Notebooks, set of 4. 2 designs, 2 of each. I'm not sure what the collaboration is. New, unopened items (one notebook was opened, and the original packaging is missing). I couldn't remove the price stickers on the outer packaging cleanly. I've applied masking tape to the areas that were sticky. Shipping will be via Yu-Mail. To prevent any issues, no returns or claims are accepted.
