They are strong and roomy much easier than using those fiddly little plastic bags for liquids when flying and of course reusable 👍 i use one for carry on luggage and one for check in main case for larger liquids ie sunscreen bags look strong and can fit a lot in there

Will be using them soon when i go abroad and hopefully will be ok through security product was perfect for putting lt100 ml liquids in it for hand luggage just what i was looking for a nice size and great for travelling
