4 in Ceramic Coasters Blank Tiles - 50 Pack for Painting and Crafts

In this review of the 4 in blank ceramic coasters, the bottom line is simple: these unglazed tiles are best for crafters and DIY hobbyists who want an absorbent, paint-ready surface in bulk. The pack of 50 comes with cork backing pads and a compact 4 in size, which makes them easy to store and ideal for projects where consistency and a writable, porous surface matter. For anyone wanting to make painted coasters, custom gifts, or testing glaze-free techniques, this set supplies reliable, uniform tiles at a modest cost.

Key Features

• Absorbent surface: The unglazed ceramic top soaks up small spills and helps prevent visible water rings on tables.
• Cork backing pads: Each tile has a cork pad that protects furniture from scratches and keeps coasters from sliding.
• Perfect 4 in size: The compact diameter fits most cups and mugs while saving tabletop space in kitchens and offices.
• Blank and writable: The plain white, unglazed surface accepts paints, pens, and other craft media for custom designs.
• Easy to clean: Rinsing with water and a light brush restores the surface without special cleaners.
• Bulk pack of 50: Plenty of tiles for multiple projects, events, or classroom use without frequent reordering.

Who It's For

The set is aimed squarely at hobbyists, art teachers, and small-batch makers who need blank, ready-to-decorate ceramic tiles in quantity. It is particularly useful for paint parties, school craft days, or makers creating custom coasters to sell, since the unglazed surface accepts paint and markers well.

Those looking for finished, glossy coasters or a waterproof, glazed surface out of the box should look elsewhere; this product is designed for decoration and DIY use rather than final, glazed protection. If you need premium decorative glazes or fully finished coasters, consider glazed options prepared for long-term liquid exposure.

Pros & Cons

Our Verdict

These 4 in unglazed ceramic coasters are a strong value for crafters and educators who need a consistent, paint-ready surface in bulk. They offer practical cork backing and easy cleaning, but will benefit from a sealing step if long-term waterproofing is required, making them a sensible choice for DIY projects and small craft businesses.
