Review on 🔥 Mylar Science Purchase: Your Ultimate Emergency Blankets by Bill Schlag

I bought 5 packs of these Mylar blankets about 2 weeks ago to line the inside of a bedroom closet that will be repurposed for indoor winter growing of fruit and veg. The blankets themselves are more like thin sheets of plastic, like regular Mylar if you're unfamiliar with them. For my purposes, these blades didn't have much play, which was a bit of a shame, but that probably wouldn't matter if used as advertised in a pinch. With good old duct tape it did the job as far as I know, and at a great price, so I'd still recommend them if that's what you want to do.
