Ever finish a DIY coaster and realize it still slides, scratches the table, or feels unfinished underneath? Or try to make a small cork board and end up with messy glue, uneven edges, and wasted material?
Meet the simple upgrade that makes DIY projects feel done: 20 Pack Self-Adhesive Cork Sheets (4x4 in, 2mm thick)—peel, stick, trim, and customize for coasters, crafts, mini cork boards, and everyday surface protection.

The Problem We Solve
Tiles and crafts need a clean backing—but liquid glue is messy and uneven.
Tabletops get scratched or scuffed from cups, vases, and small décor.
DIY projects stall when materials are bulky, hard to cut, or over-purchased.

Why This 20-Pack Works
1) A practical 20-pack for real projects
Enough sheets to finish multiple coaster sets, small cork boards, and craft builds—without buying 50/100 packs that sit unused.
2) Peel-and-stick application—fast and tidy
Peel the liner and press onto a clean, dry surface. Great for adding cork backing to ceramic/glass tiles, craft bases, or quick mini note boards.
3) 2mm (0.08") thickness for better cushion & protection
The 2mm cork creates a soft buffer that helps reduce minor sliding and everyday surface wear—ideal for drink coasters, vases, and tabletop protection.
4) Easy to cut & customize
Trim into circles, strips, labels, or custom shapes using scissors or a craft knife. Decorate the cork surface for personalized gifts, seasonal crafts, and classroom projects.
5) One simple material, many uses
Use as coaster backs, mini wall cork squares, small-area liners, furniture pads, or craft bases—a flexible staple for home and maker spaces.

DIY coaster makers (tile coasters, wood coasters, resin coaster backs)
