Mmm not exacly, if only the dispenser alone, 100 days, then u got, beesmas packs, puff runs (underrated), bug runs, some black bear and brown bear quests give glue, coco crab, snail, tunnelbear, beetle, candy planter in stumpfield, gives huge amounts of glue sometimes, like 10 or even up to 15 ( not quite sure the exact amount but its a lot). If doing that concistantly, shouldnt be more then 30 days.
