**Leak-Proof 3oz TSA Approved Silicone Travel Bottles – Refillable Squeezable Toiletries Containers for Shampoo, Conditioner & Liquids | Perfect for Air Travel, Gym & Camping**

I was nervous they would pop open in my bags but they didn’t they close well and will definently be getting more since you can never have enough travel bottles and fits a large amountEasy to fill and great quality!These are similar in material and appearance to a set bought several years ago that performed well for travel. In my experience, this set had problems with leaking due to pressure changes in the airplane cargo/luggage compartment, causing some of the contents to leak from the container inside my suitcase. Also the slits in the cap open to allow dispensing the bottle contents only with higher pressures, causing a sudden release of the contents that was messy and I could not control.I put them in a checked bag and they didn’t leak one bit during travel! Super impressed and I love how soft and squishy the silicone feels. My friends commented on how nice they felt too. Also loved that they came with labels. 5/5AwesoneI used one of these bottles for massage oil and thought i could easily squirt the liquid into my hand as needed but when i tried squeezing these bottles the liquid came out in short unexpected bursts that was not controllable. I don't recommend getting these if you want a product that releases liquid from the squeeze cap in an easy to use manner.
