YINO 3 IN 1 Travel Magnetism Bottle Set Empty 96ml Plastic BPA Free Air Travel Bottles and Jars Toiletries Liquid Containers for Cosmetic Makeup, Shampoo,Lotion,Sunblock (Black)

I like unconventional travel items, and I was really excited when I found these. Maybe I'm just an idiot, but I thought these were supposed to be TSA compliant. When I received them, I couldn't fit the cylinder into a 1 qt. Bag. Instead I had to break them apart, and still had to really squeeze them in (broke two bags in the process). I returned them because they were to big for my carry on. However I did put liquid in one and tried it out. Works great, especially in the shower (not a ton of bottles to carry). If you're putting it in your checked bag - it'll work great for you!
