Review (5/5): LOVE these!  What a deal!
Perfect size for my style of travel. I don't need 3 oz. containers when these 2.4 oz. ones contain more than enough product--leaving room to spare in my TSA one qt. bag.
Great quality, absolutely LEAK-PROOF!! Love the non-slip raised designs and the beautiful color assortment to differentiate between products. Also, they stand up easily, do not roll off a counter and have a very secure snap-on flip cap.
When some product has been used from the container, gently squeeze out excess air, then the container compresses to offer even more space!
The smaller, round screw top containers are made of hard plastic (not silicone) but are a great size for smaller items or gels.
So glad I got this set, and can see many years of usage traveling with these convenient, beautiful containers!
