I really like that it has a removeable adhesive. Makes it so easy to postion and make sure it will stay put while stamping. You can also cut it to fit your project needs.
This is the first mask that I've ever bought, so I was surprised at some aspects of it. First, I think the quality of the mask itself is great, very sturdy. It worked great to ink the swirlies onto a page. The adhesive was REALLY sticky, which made it hard to peel it off the base and it did do some damage to my cardstock when I pulled it off after using it. Perhaps it will become less sticky over time and those problems won't last. Still, it's a great way to add some interest to a layout.
Love this mask! So easy to use. I need to get a new one though, because i accidentally embossed the swirls without moving the mask and found out after i pulled it up i had used it wrong side up so its not sticky anymore! Yikes!
