12 Pack 4 x 4 Inch Gorgeous Black Slate Stone Coasters Bulk Square Slate for Drink Bar Kitchen Home, Handmade Natural Rough Edge, Set of 12

The box arrived a little crushed (the fault of the delivery person somewhere), but the interior box was safely nestled inside. Not one coaster was broken as they were adequately protected. These square slate coasters are perfect for laser crafting. They are a good thickness with protective feet already adhered to the bottom. I laser quirky sayings on the front and then my brand on the back of the coaster. The low price makes it affordable. They do not stain. I will definitely purchase these again.

I use these coaster for laser engraving projects putting peoples logos and sayings on them. The quality is good. I sometimes find one in the package that doesn't meet up to my stands for selling to customers but the price is right and 1 or 2 with a chip or a defect on the face still makes it worth the purchase.They come with 4 foam feet on the bottom. They come with a plastic wrap around each bundle and then inserted into cardboard for more protection. I have bought a little over 200 so far and have been pleased with them. Recommended. JohnnyF

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

I have ordered these multiple times for my side hustle of laser engravings, I use them for making coasters. They engrave beautifully with a light coat of clear acrylic applied before engraving. Gives it a good contrast. I have a ton of test ones laying around the house for use and they have held up super well. None of them had broken or worn down yet with repeated use. And 60 coasters for this price is a steal, allows me to make some mistakes while engraving without feeling like I wasting money. Highly recommend these. That being said only issue I have had is with it being natural stone the thickness can vary, which can cause some of the rubber feet to be not level, so there is a little wobble. But I only get maybe 3 out of 60 coasters that do that and just use those as test pieces.

I have used my CO2 laser on the slate costars, they came out well, I gave them a light coat of clear lacquer before I using the laser. Like others have said they very in thickness and size, but they are made of slate you can’t expect them to be perfect. None were chipped or broken. I will buy them again.

Using these to engrave images on (both custom and stock images). Take to the laser well and come with little rubber “feet” so we can just engrave and sell without a lot of time or setup required. Thick enough but not bulky. Just what we wanted and will buy again. Kind of a rustic chipped edge on them. Hey they work.

When you buy slate blanks like this, you're gonna have breaks. It's just part of the game. These were well packed and the good ones are perfectly fine. I would only have maybe one in a pack broken, but the price is good enough for me not to care. The project is just fun

Perfect. Recommend!
