  • Good
Size: 500 Count
They complete heir function and are not transparent. The price is incredible. The security they have is so amazing. They peel well, and the color is impressive. Good weight

  • Good thickness

They are very nice. I like the thickness. I’ve had some that are flimsier and thinner. These are much better quality.
