Unused sticker backing sheets. Medium thickness & white. 50 sheets per pack x 3 sets. These are unused, professional-grade sheets, so there is absolutely no adhesive residue or sticker marks, and no peeling of the release agent. Perfect for storing stickers, etc. Also, the release force is standard, so: - Stickers and tape will adhere normally. - They can be peeled off cleanly. ☆ Construction: Only one side (the adhesive side) is laminated and silicone-coated. ☆ Thickness: 0.12 mm (medium) ☆ Size: A4 size ☆ Release force: Standard (stickers and tape will adhere firmly) ※ Adhesive compatibility may vary depending on the adhesive used. ※ These are machine-cut, so there may be slight size variations. ※ Packaging: Cardboard to prevent folding + PP bag to prevent rain damage. Shipped in an envelope via Yu-Yu Mercari delivery. I will send a slightly larger quantity, so please refrain from returns. Please purchase with the understanding of the above. #ReleasePaper #ReleaseLiner #ReleaseSheet #PeelOffPaper #HakuriPaper #Sticker #StickerBackingPaper #StickerBackingSheet #StickerReleasePaper #Separator #Sepa #BackingSheet #HalfCut #CutOut #FlakeSticker #StickerRepositioning #DoubleSidedTape #MaskingTape #StickerBook #StickerNotebook #Seria #Daiso #KyowaPaper #Kyowa
