Acrylic positioning block for clear stamps and rubber stamps. Perfect for your scrapbooking and DIY cardmaking projects, acrylic blocks allow for greater precision and visibility. Thanks to their transparency you can easily place your stamps, positioning and aligning your designs without mistakes. Transparent stamps are always used on an acrylic base because they do not have a base like wooden stamps. Use: Place your transparent stamp on the positioning block, ink it with the ink you want and stamp using the transparency of the acrylic block. Positioning blocks are essential as they allow for a greater hold. Product dimensions: 15 x 5 x 0.5 cm.
