72 PCS Black Slate Stone Coasters, MAPRIAL 4 Inch 36 PCS Square and 36P Round Coasters Bulk for Laser Engraving Material Blank Handmade Drinks Costers for Engraver, Etching, Gifts, DIY

Best deal I have on bulk slate coasters. Uniform size and quality.

Super value and very nicely made. These were better quality than some sets of 4 and 6 that I bought. Great value and these engrave so nicely. And, they have 4 nice rubber feet on the bottoms to keep from scratching your table that are very securely adhered. I would recommend this.

Works great, great price. I just placed fourth order.

Look great and well packaged. No broken ones yet. Good variety between round and square coasters. Surfaces are clean and easy to engrave with laser. The only concern would be coasters vary in thickness by a good amount. Will provide pictures later.

These coasters are so great for my laser engraving company. They have a consistent thickness and very durable.

Fast Shipping, excellent quality of the material, the engraver quality is amazing give me excellent results at the moment to engrave to my customer, they are very satisfied with the results, I will buy more of this product soon as possible!!!

I have found these slate coasters to be easy to work with. I have bought and used up almost two boxes worth, ( 144 ), and love the look and feel of the coasters.I engrave with a Longer Ray5 10 watt machine set at 165 inches per min at 95% power.Perfect results every time. Only had to use/lose 1 coaster to run a materials test in Lightburn before finding the above perfect setting.Just ordered my third box of 72 mixed round and square. Have not received any broken or unusable coasters.

I use these to laser engrave on they look awesome. I have made them for my business. Great quality.
