Review (5/5): Wonderful idea. Just beware of bulk.
Since I’m now very particular about which shampoo and conditioner I use, I no longer rely on what hotels provide. I sought out for good travel containers. These are great. I love them. However, since I always travel with a carry-on only, these great but bulky tubes (I only needed to bring two, still!) took up so much space and I couldn’t fit all my other liquids in the quart ziplock bag. I think I’ll only use these for car traveling and on rare occasions when I opt to check my luggage. Still, great set. I especially appreciated the little tiny funnel to transfer toner to a little spray bottle. (That was really the reason I chose this set over zillions other sets!)
