Document: These coaster are ok they do the job. I will order more when needed. Thank you for a this producer.
great coasters we have so much company we use these a lot and then we can just throw them away
Wrote a review for the square coasters. Same review applies to these. They soak up ink about the same way they would soak up water
The coasters work well as they absorb  the ice moisture without  soaking through to the table for a reasonable amount of time.
I have no idea how these work as bar coasters, but they are perfect for my Zentangle project. Nice weight, texture and size.
for the price, you get a lot of coasters...could be a bit thicker and smaller, but am happy with them...would be fun project for kids to decorate
I love the coasters. I use them as a canvas to create little pieces of art! I also bought the square ones!
We bought the first set of these for our camp. One of them had a coffee stain and I just turned it over and used for another couple weeks. For the price, these coasters are a bargain.
Great for coasters and also to frame....love them to zentangle on. They also take water color quite well.Great price for so much fun.
It's a simple product, but not easy to find at a fair price. These are great as-is but the 50 I bought are destined for craft projects from coasters to ornaments to air fresheners.
Answer: Yes they can. Acrylic paint is best. You can also add stickers to them. I added monograms to a few. The rest I just left as is. Enjoy your coasters.
