Review on 🍓 FRUITEAM 4 oz 12 PACK Mini Mason Jars: Quilted Crystal Jars for Food Storage, Jam, Body Butters, and Wedding Favors by Richard Marriott

I haven't been able to open this box for weeks, so I missed the return deadline. The accompanying literature for these glasses states that they are not heat resistant. It specifically states that there are no microwaves, ovens, or freezers, so actual canning seems out of the question. It also states that glass should not be exposed to extreme temperatures. This makes it useless for the advertised "jams, jellies, preserves, canned goods, fruit syrups, chutneys" deal. Looking at the description, part of the decorative part of the listing says "Please avoid extreme temperatures". Pointless purchase and waste of money.
