Very happy with these wind spinners. They are easy to press, easy to open and they hold up very well. My sublimated prints come out so vibrant and look great. Definitely worth it! I’ve ordered these multiple times!

These are amazing gifts.
I think I've reviewed these in the past but they are my favorite thing to make. They are stainless steel so they don't fade unless they are in direct sun. You can put any sublimation print on them (peel off the plastic first) w an Epson 15000 sublimation printer or an 8550. They are 10" not 8. So you need the bigger printer.
