i love all thickers. these thickers meet all of my requirements for an alpha: the fonts are wonderful, they're very bold, the chipboard is sturdy and the adhesive adhears very well. as a bonus, always have enough letters to do 2+ LOs in a single pack. i dont know how, it just always works out that way. knock on wood!
the glitter on these guys are definately a bonus.
The chipboard itself is great. The glitter gives it texture but doesn't rub off like on other glitter-coated items. I probably have almost one of every kind of Thickers by now. The only drawback is that the adhesive doesn't always adhere very well. Picking up the LO or doing additional work on the LO will cause the Thickers to pull away from the paper. I've found that I've had to add additional adhesive in order for them to really stick.
