Hi Marina,
I’ve been printing on these for the past 5 months and they have pros and cons.
Pros:
– super affordable
– fast shipping
– accepts impression well
– photographs well
Cons:
– printing surface is fluorescent white. I print mainly with “pearl white” paper, so in comparison the coasters look… cheap. However by themselves they look fine.
– edges are off-white, almost dingy.
– they do tend to crack – especially if you have an enclosed impression like a circle, or small type. However if you get the packing just right cracking is no longer a problem
– doesn’t accept a deep impression (cracking)
– they come with these itty bitty tabs on the edges. I assume from cutting. Not a huge deal.
– they get soaked under a normal glass with ice. I worried about it ruining my table, but it somehow didn’t.
– After they dry from beverage condensation they have permanent water marks. Think if you were to set your glass on a stack of regular printer paper.
– I would say they are totally unusable after 5 uses.
Ok, all that being said, I love them. They sell like crazy. You can sell them for pretty cheap (set of 6 for $8) and still make a good profit. They work out to .03 each so really customers are paying for the ink, polymer and labor. I use them for my business cards and people love them. I’m writing a blog on them as we speak, and I’m even thinking about getting the heavy stock. Paper source just started selling some nautical ones (I started selling them first! haha) and theirs are the heavy stock.
I hope my review helps you make your decision! 🙂
Happy printing,
Christy
