Strathmore watercolor paper. I believe this is a discontinued item, so it's quite valuable. Paper texture: Medium Medium weight: 300g/m2 Bound book, 12 sheets Strathmore Book IS-SM Spring [Condition] New, unused. Although it is a new, unused item, it has been stored for a considerable amount of time. I opened it once to check the contents, and it appears to be fine to the naked eye. However, please understand that there may be some age-related deterioration due to the long storage period. Please refrain from purchasing if you are sensitive to such issues.
