I have 2 10 oz bars, and the original plastic is torn and frayed. do they make airtites to hold bars? what kind of alternative storage methods do you recommend? should i just put them in a ziplock bag?
If you have a food saver vacuum sealer, those work good. Ziploc is just as good. I have heard on the forums here to store them with a few wheat pennies to ward of tarnishing but haven't proved that out. Really and food service type storage is good. No PVC.
Depends on the type of 10 oz bar really. Some kinds have airtites made for them and some don't and not all 10 oz bars are the same dimensions and come in many different shapes and sizes (Which i love).
Personally I wouldn't spend the money on airtites, its a generic bar. In fact some people will pay more for them if they develop interesting toning/tarnish.
