Great for Sublimation
Size: 8 Inch, Size: 8 Inch
These are just the right size for using with 8x10 printers and Cricut machines.
When printing on sublimation paper, the colors come out vibrant and clear. While I've purchased these from other vendors this is the cheapest price I've found in bulk.

Best size for standard printers.
Size: 8 Inch, Size: 8 Inch
Great value and these spinners sublimate wonderful. Also great he 8” works the best for the standard paper size,
The 10” is too big and it’s not fully covered.
