Review on 200-Pack 3" X 3" Clear Plastic Reclosable Zip Bags | Heavy Duty 4 Mil Thick Poly Baggies With Resealable Lock For Travel, Storage, Packaging & Shipping by Frankye Sherman

These plastic envelopes are strong enough to use and reuse for keeping chunky metal jewellery making parts in, or for filling with liquid sauce that doesn't leak out if you lay them on their sides. It's worth it to me to spring for the few extra bucks and get this heavier duty bag that doesn't puncture as well as other lighter plastic bags might do. Great for organizing small junk, and very reusable.
