Potchen 60 Pcs Cork Coaster Bulk 4 Inch Round Cork Coasters for Drink, Absorbent Heat Resistant Drink Coaster Reusable Blank Coasters for DIY Crafts Laser Engraving Tabletop Protection Party Decor

Only slight con is there is a small amount of cracking/flaking on the bottom edges but it’s very minimal and can’t be seen from the top side..and only if you look really closely.Other than that amazing quality and quantity for the price. Took some time to find the sweet spot power/speed settings on my laser but once I found them they just engraved beautifully. Clean, crisp black lines. Smudging as to be expected with lasering cork, but a couple light coats of a matte clear sealer stops that issue. Super excited to start selling laser engraved coasters with these in my Etsy shop! Great value for small businesses on a budget

The Potchen Cork Coasters are excellent coasters for a person who wants to produce gifts or crafty coasters to sell. I laser burn on the coasters to make custom gifts for the clubs I am in. These are heavy duty coasters, over 2mm thick which is nice. I use them at home and work.They take paint, stain, and laser burning very well.I found that with my 10watt optical laser, I run the servos at 100% speed and the laser set at about 30% intensity. That makes a very clean burn.

I research a lot for good products for my art projects and liked the quality and value of these cork coaster bottoms for my concrete coasters

Great quality and impeccable sturdiness. I will be buying more for projects at work.

nice product

Good value for the money. These cork coasters laser engrave nicely.

Bought these to make chips for a giant Connect-4 game for my daughter’s wedding. They’re the perfect size. I did have to double them up to get the correct width but there were so many in the package I was able to do so with leftovers.

These are nice coasters. I am using them to make custom coasters. They are actually only 3.88" so adjust your measurements if you're using these to make other items
