Just didn't work effectively. I once figured out how to apply them without touching them (leave half on paper and apply to shirt, then peel off paper and press collar against sticky material). It's really sticky and I wasted it trying to find it, determined not to stain the sticky that way, but even then they wouldn't hold the collar in place. I recommend a magnetic collar. The ones I have are from Wurkin Stiffs and they work GREAT. Solve an annoying little problem that has always bothered me. No, no financial interest in either company, Wurkin Stiffs is just a great product.
