3.75 in Hexagon Blank Ceramic Coasters - Unglazed Tiles for DIY Crafts

In this review the 50 Pieces 3.75 in Hexagon Blank Ceramic Coasters are evaluated as a craft supply and functional tabletop protector for home crafters and hobbyists. The bottom line: these unglazed tiles are best for people who want a paintable, absorbent surface and consistent coaster size for alcohol ink, acrylic pouring, epoxy or mosaic work. The review finds the coasters deliver good value and craftability, with an absorbent ceramic face and cork backing that prevent surface scratches when intact.

Key Features

• Absorbent surface: The unglazed ceramic face soaks up small spills quickly, helping reduce visible water rings on wood or other surfaces.
• Perfect size: At roughly 3 3/4 in by 3 3/4 in, the hexagon tiles fit most mugs and cups without crowding a table.
• Blank and writable: The unglazed finish provides a matte, paint-ready surface ideal for alcohol ink, acrylics, epoxy and other craft techniques.
• Cork backing: Each tile includes cork pads to protect furniture from scratches and to help keep coasters from sliding.
• Natural materials: Ceramic tiles and cork are made from natural materials that accept paint well and dry faster than glazed alternatives.

Who It's For

These hexagon coasters are aimed at DIY crafters, art teachers, and hobbyists who need a sizable pack of uniform, paintable coaster blanks for projects, parties, or classrooms. The pack of 50 makes them especially useful for group projects, craft fairs, and makers who want to experiment with multiple techniques.

They are less suitable for buyers who need prefinished or waterproof commercial coasters out of the box, or for those who cannot tolerate occasional shipping damage; some users report receiving broken pieces and variable adhesive strength on cork pads, so fragile handling or replacement expectations should be considered.

• Good value for quantity, allowing many experiments and practice pieces.
• Paint-ready, unglazed surface with a pleasant matte texture that accepts inks and paints well.
• Cork backing reduces scratching and helps keep coasters stable when present and well adhered.
