48 PCS Slate Coasters for Laser Engraving, Natural Stone Drink Coaster Bulk | 4 Inch Rock Blanks Coaster Set Home Decor with Anti-Scratch Pads for DIY Crafts, Painting, Kitchen, Bar, Party, Square, Black

I purchased these specifically for use with my laser engraver, and I could not be happier with how beautifully they engrave. The contrast is stunning. The natural dark slate turns a soft, crisp light gray when engraved, which makes even fine line detail pop. I’ve engraved botanical designs, animals, intricate line work, and geometric pieces, and every single one came out clean and sharp. What I especially appreciate: • The surface is consistent from coaster to coaster • No strange patches or uneven density • The edges have a nice natural chipped look without feeling fragile • Thickness is uniform • They sit flat and don’t wobble For anyone wondering about detail capability — yes, they handle fine lines extremely well. I’ve been able to capture small feather textures, fur detail, and delicate plant line work without losing clarity. They also arrived well packaged with no breakage, which is always a concern with slate. If you’re using a diode or CO2 laser and want reliable results with strong contrast, these are an excellent choice. I’ve attached photos of several different designs so you can see how they engrave across different styles. Very impressed with the quality and consistency.

These slate coaster are great. Engraved my logo on top and look amazing. I highly recommend if you want to do your own custom work

Good value, excellent quality. Highly recommended for laser etching!

I have purchased a lot of slate coasters to use for laser engraving. Slate coasters are a natural product and there will always be imperfections. Overall this was an ok batch. I scrub the surface of slate before engraving to remove any manufacturing residue and flakes. These were fairly clean. They were wrapped in pairs in bubble wrap. There was no damage. These are about 3 7/8" square. Most had consistent borders. There were some that were different thicknesses. Most were about 3/16", some were close to 1/4". About 10 of them had surface defects with quartz particles or divots.

Yes! Great size and value

I purchased these as a project to do with my sister during a crafting day. We etched mandalas with Armour Etch and they turned out beautiful.

Good quality and comes with the foam pads on bottom. Wrapped two to a pack so they don’t get damaged. Great for engraving

Slate coasters were all intact , no damages . They were packaged very well. I recently purchased a 60W mopa fiber laser and my custom coasters turned out great.

Really pleased with my purchase

Très jolis dessous de verre qui donne un excellent rendu sur une table !

Gute Qualität. Lassen sich perfekt laseren

Good quality, ideal for laser engraving. Good price too.

Yo, what's good? Just copped these Slate Drink Coasters with Leather Holder and they straight fire, you feel me? The leather holder keeps them all together and looking fresh. And the slate material keeps your cup or glass from leaving a ring on your furniture, you know what I'm saying? I'm giving these coasters a solid 4.5 out of 5 stars. They get the job done and they look boss while doing it. If you're in the market for some new coasters, these are the ones to cop. Peace.
