【Acrylic Stamp Pad/Stamp Surface Finishing Plate】 ＊Made of acrylic (white) ＊Approximately 110mm x 110mm, thickness approximately 5mm ＊1 piece When stamping your work, commercially available stamp pads tend to be soft, often blurring the stamp impression. Professional seal engravers use glass or acrylic plates to create clear impressions. You can place a piece of Japanese paper (washi) between your work and the acrylic plate to adjust the hardness to your preference. Also, the flat acrylic plate is useful as a backing when smoothing the stamp surface with sandpaper. 【Waterproof Sandpaper】 ＊Approximately 23cm x 9.3cm ＊1 piece This is 600-grit sandpaper, perfect for finishing stamp surfaces. Cut it to a size that is easy to use. Apply a few drops of water and hold the stamp material vertically, moving it in a circular motion to smooth the surface. The key is to be gentle and not apply too much force. Rotate the stamp material up, down, left, and right, and smooth each side in the same way. It can also be used to re-smooth a stamp surface that has been incorrectly engraved. ※The acrylic plate has protective paper attached; please remove it before use. ※Both the acrylic plate and sandpaper may have minor scratches or stains that do not affect their use. Please understand this beforehand.
