Thank you for viewing. This is a set of two Casper tapes. They are not masking tape. They have been stored at home in a dark place. The diameter of the core is the same as cellophane tape. They have been stored at home for about 10 years, so there is yellowing on the inside. We cannot guarantee the adhesive surface. Please purchase only if you understand this. Instant purchase is welcome. Please refrain from price negotiations. We do not offer dedicated or reserved listings. Please purchase after understanding that these items have been stored at home for a long time. Thank you! Harvey Comics Hot Stuff the Little Devil Casper Masking tape Cellophane tape Cellotape
