My stickers are "almost" perfect...!

we've been test driving the new "roll" stickers to seal up our butcher paper sammies at our restaurant, The Dirty Pickle! Quality of the sticker is awesome and so is the printing!!! Our only hope is that the adhesive, actually becomes more "sticky"!!! Currently, the stickers get tired of holding our sammies closed after a few minutes, maybe they need to work out more!!!
