My pack with these in them arrived today, and I have already used one on a lo. They are beautiful - made with some kind of leaf which produces the vein on the wings. Delicate enough to look really pretty, but sturdy enough to survive glue dots or whatever else we scrappers will do to them!
The newer ones are nicer. these had a lot of glue on the body of the butterfly. I am still happy with the purchase. I love everything Prima makes.
