Used to be great, now not so much
Size: 8 Inch
**update** TOP NOTCH customer service. Seller messaged me very quickly after the 3 star review and was very concerned that their product wasn't as expected - made it right for me and I will definitely give them another try! I have purchased these several times, and at first I would have given a 5 star. I love the way the come individually wrapped and they use to come with a protective film on it. They still come individually wrapped, and no protective film now. Only 1 side sublimates very well (great colors). The 2nd side is duller and it's noticeable. I will be looking for a new supplier unfortunately. I wish that I could say I still loved them, but something changed!

Great wind spinners, you can't go wrong
Size: 8 Inch
5 stars is not enough for these. OMG I found my new supplier for the wind spinners. I have gone through four other suppliers and they did not turn out well, for various reasons. But these I love for a couple of reasons. First I love that they have the paper on them for removing the plastic, holy cow was that easy! Second I love how they turn out for the ones I already made. They sublimate beautifully and the colors really pop. Thanks so much, and I'm going to order more right now! I hope you don't change them. I do recommend these folks, they are awesome.
