Winter is coming. Forever.
The issue of a can sealer in another thread bright me to this question. I've always wanted one, but TBH I haven't researched beyond pricing and a "the best" type search. The question is, how do you know when you've lost a seal? With Mylar I can generally, simply tell when I lose a seal. I go thru once a year and pull any bags not sealed and eat it up. If there's no way to tell, I'll mark it off my list now and change my shelving design. More Mylar means more totes.
