Premium Aluminum Travel Bottle Set with Leak-Proof Lids & Carrying Case - 3pc TSA Approved Toiletry Containers for Shampoo, Lotion & Cosmetics | Ideal for Air Travel, Gym & Camping Trips

The bottle sizes were ideal for me and they had a smaller opening, however they smelled horrible. The bottle body is aluminum, but the part that the cap screws into is a separate metal, gold in color and the bottle reeks of a glue type chemical smell. The smell did not go away after washing. I was not willing to risk exposing myself to whatever chemical was present. I tossed the bottles into the trash. Not worth the effort to exchange and I'd probably get the exact same bottles and problem. Additionally the case is not insulated.
