Review (5/5): Best travel bottles
I love these. I travel frequently and I have never had any issues with leaking. They are durable and easy to refill. I am sad that their company site is no longer running because it was the only way to buy the bottles you want or individually instead of whatever is available in a set.
Based on a week of travel...
The 0.5 oz is great for moisturizers, face soap, toner, etc.
The 1 oz can cut it a bit close for shampoo or body wash, depending on much you use.
The 1.7 oz is plenty for shampoo/body wash.
These also work great for stuff like sunscreen, leave in spray conditioners, hairspray and other liquid-based beauty products.
The labels are durable and easy to apply. The travel set bags are just fine, just note they aren't the "quart size baggie" wanted by US security. But the bag has a zipper and is very durable and can be used for whatever.
