Review on 15 Pack Woozy Bottles 8.5 oz - Leak Proof Screw Black Cap, Shrink Capsule, Snap On Orifice Reducer Dripper Insert - Round Glass Bottles for DIY Hot Sauce, BBQ Sauce - Perfect Christmas Gift for Women by Garon Tafolla

Bottles arrived quickly and at a reasonable price for their size. Although well packaged, they all have signs of rubbing against each other. I've tried cleaning it (first photo) but it seems permanent. The caps and plugs are of decent quality, with a hollowed out area in the cap that seals the plug when screwed on, but the supplied gaskets were crushed and basically unusable. If you use them for yourself and don't care how they look, they're fine. If you're hoping to use them for gifts I'd keep looking.
