EK Success, under both the Zig and Martha Stewart names, makes a glue marker in several different sizes. One is a very fine point, one is medium, one is a thick chisel, and one is a very wide "square." I've used all of them, and I've never had any warping or buckling. You do have to use a light touch, and not apply puddles of glue; but with fine glitter, you shouldn't need puddles to adhere it. I hope this helps.
