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.

High quality
Size: 8 Inch
got these to make some spinners for our football team and found them to be terrific. The image transfer was true to color and the size was perfect. We are going to make a few as gifts for our friends and thought the pressing of the tines out to create the spinner was quite simple. Will definitely be ordering more.
