Pros : The decals were easy to use, and fired fine. Having practice decals and directions in the package was very helpful.
Cons : Although the decals themselves were OK, there were a lot of decals that were not full snowflakes. On the sheet, about half were unusable, because they were only half a snowflake, and some even less than that. I. Had to be very careful cutting them out, because more than once, there were pieces of a part of a snowflake stem on the decals which was ready to use. Most of the times, these were not even visual before I put them on the glass.
