Sweese 3405 Cork Coasters - 4 Inches Perfect for Most Kind of Mugs - Protect Your Table from a Liquid Ring - Set of 10

These Sweese coasters keep my table dry. As there is a rim and condensation from glasses collect inside. They don't scratch. The only thing that you may not like, when the coaster gets wet, it holds onto the glass when lifting the glass. This never happens with cups. I like that the coasters protect your table from hot beverages. Easily wipe clean. The only con: do not come with a coaster holder and Sweese doesn't have one to purchase.

I love these cork coasters. Purchased to add to the few I already have. Drips from glasses stay within coaster. Lightweight & work great!

These coasters work great for my needs. I followed another reviewer's advice and put felt circles inside them to absorb most of the condensation from the sides of the glass.

They are great, they are very cute and fit well even with mugs that have low handles. The only problem that I've seen so far is that when I have a cup/drink that sweats a lot the condensation will pool in the bottom. I've had to pour out condensation and set the coaster aside to dry. So far I've only had this occur with glasses rather than ceramic cups. Also, if there is no texture to the bottom of the glass you're using, the coaster may stick due to the condensation. I like them and they work for my purposes even if I have to take extra care at times.

so I originally had bought these for my fruit baskets that are out on the counter, because I read they keep them from rotting faster and fruit flies at (which they did); but I also use them for coasters and they keep all the condensation off the tables as well as not sticking to the cups. Highly recommend if you want for coasters or for keeping fruit fresh and flies at bay.
