24 Pack 4 x 4 Inch Gorgeous Black Slate Stone Coasters Bulk Square Slate Stone Cup Coaster for Drink Bar Kitchen Home, Handmade Natural Rough Edge, Set of 24

I use these for engraving with my lp4 and they work perfectly the quality is great I've ordered some from other Sellers and they just weren't consistent these ones are great quality thick consistent and engraved nicely.

Great coasters for laser engraving on. They're highly durable, resistant to heat and moisture, and easy to clean. Each coaster's unique texture and color variations make them a stylish choice, though they may be a bit heavier than other materials. Overall, they’re an elegant and practical choice for protecting surfaces

Use these blanks for laser engraving. Good quality and great price. Will be ordering again.

These are really nice slate coasters. They have the back bumper pads on them already. My only complaint is there is variation on thickness so you have to try to match them to make sets. However, this probably is to be expected as it is a natural material. They laser beautifully!

These come packaged so well that there’s little chance of damage. Shrink wrapped in sets of five, with three sets tightly packed in a three n box, with four boxes packed tightly in a good shipping box. NONE damaged.They’re good quality as well!

I love these slate blank coasters are so perfect for laser engraving... great buy!!!

bought these as my others i normally bought were out of stock, now the others are a thing of the past, these laser great with my xtool d1. will continue buying these as needed!

Thus far, super happy. I've engraved 10 of them with my XTool M1 at the Stone Coaster setting and they're perfect. As others mentioned, they're not all the same thickness, but do seem to be the same 4"x4" dimension, which is what I really care about.

Items of less quality than previously ordered coasters of the same price

All arrived in great condition and will be back again for sure.

Just what we needed. Perfect size and good quality slate.

The round slate coasters are as detailed within the description. I have laser etched designs onto these coasters. Recommended to all.

Unable to give review as we are yet to receive all our order, as in we don’t have the machine that we purchased to use these with. No delivery date given yet - 1month later and still waiting.
