36pcs Natural Edge Slate Drink Coasters - Stone Bar Coasters for Drinks, 4 Inches, Square &Round Ideal for Coffee Tables, Outdoor & Home Décor

Good product overall. Very happy with our purchase. Came well-packaged with no chips, cracks, or breaks. Size was as-advertized. Nice color, look great on the table. Durable and perfect for crafting. The little feet protect the table-top or counter while keeping the coaster in-place with no unwanted sliding or movement.

Not one was broken. This was my first experience with buying slate. I'm sad to say that my next order I didn't go with this same company. I figured it's a 4" slate coaster and slate is slate, right? Wrong. That other batch was so thin you know the same folks who make copper wire from fighting over pennies had to be involved. The edges felt like they might cut you if you weren't careful. So back I am to order from this producer.

I gave 5 stars but I want to warn people what I learned the hard way that there is some variation in the thickness from one coaster to the next. If you are ready for not it’s no big deal but it can get hung up on your laser engraver. Just be aware. Otherwise excellent product. The feet are very well attached

I got these to use with my laser to make coasters for friends, family and to sell. The laser engraved them very well. They work well as coasters and absorb water very well as a coaster. Some people engrave them and then seal them with polyurethane but then they wouldn't absorb well. They look good engraved or not.

The media could not be loaded.  We Enjoyed sampling your product for my engraving business Whats the Point Designs . The quality is great. And the engraving were clear and concise. Printing on Black slate looks elegant. It is great for baby showers, weddings, birthdays and housewarming parties or personalized gifts. Personalized products can increase the value of any gift for years to come. And Black slate allows customers to purchase their materials and make it special. The quality is heavyweights although it is thin. The color does not peel or crack. I will definitely use this product in the future. Thank you

These are absolutely the best coasters for Engraving. They don’t chip or crack. Highly recommend these and will be buying more

We buy these all the time for our business. Highly recommend these!

A little pricey and they are a bit small, not a full 4 inches. Other than that they are ok, stood up to some laser work and look nice. I bought the 8 pack 4x4 square.
