Sizzix 661560 Framelits Die Set, Circles, Dotted by Stephanie Barnard (8-Pack)

Thought all Sizzix products were guaranteed to work with their machines but this is not so. This bit horribly into the plate leaving the rounded bits deeply embedded in the plastic. You can feel the roughness when you lay a different paper on and you cannot remove them. I tried spraying with water. I tried using alcohol. I tried rubbing with my fingers. Nothing! Other than digging them out using a needle, which will probably cause more damage to my plates, they are stuck there forever. It got worse trying other coloured card. I thought the round bits would gently emboss into the circle, not cut through it. I am truly disappointed and considering complaining to Sizzix about it.
