These are game changers for packing! I now have a couple of sets and am getting a third because I now want absolutely everything in my suitcase contained in one of these beautiful, sturdy, and roomier than you'd think zip bags. The vibrant patterns are gorgeous and the nylon is super light weight but SOOOO durable. I pack these to the gills and then compress and zip. Never had any issues with zippers or seams splitting. Makes my luggage much more manageable and compact. Larger bags I use for bundling outfits, rolled up clothes, keeps things organized, tidy, and clean. Medium bags used for undies, socks, pjs, etc. Small bags are great for toiletries, supplements, snacks, jewelry, electronics. Then when you are living out of your suitcase, you can grab the bag you need without rustling through and messing everything else up. Have gotten so many complements and inquiries about them and can't recommend them enough!
