My colleague Abby Kass has them and loves them too! “I recently got a set of four and, wow, I love them so much,” she said. “I used these recently on a six day trip and they were perfect. I customized the label for which was my shampoo or conditioner and created a general label for all the other things that I wanted to carry. They hold a surprising amount. Depending on the brand, they hold about one to two weeks of skincare products, over two weeks of serum, two to three days of haircare, and over 15 tablets ( for medications and such). And while two to three days of hair care doesn’t seem like enough, I found it was enough for me, but I also don’t wash my hair every day. It was small enough to slip right into my toiletry bag. and go through TSA with no problem. The container was easy to open in the shower (even with wet hands) and I had no leaks. It’s an incredibly useful tool that all those who travel will want.
