Silicone Travel Bottles for Toiletries TSA Approved Travel Size Containers Set 4 Pack Portable Leak Proof Refillable Cosmetic Squeeze Bottles Shampoo Hair Conditioner Body Lotion Bath Shower Gel

Not sure why I hadn't known of these before. Used these on a 2-week trip without problem (I do put these in a quart ziplock bag to contain any spill - no leakage noted though). I use one for face wash, one for shampoo, and another for toothpaste. One thing I found interesting is that a 5-ounce tube of AIM toothpaste will fit in one of these. I now keep all three tubes in my carry-on toiletry bag.

Work well, I like all the colors to identify what you have in them.

They are well made, seal well and easy to open

Well made and designed

Yeah they work well. They haven’t leaked yet after 5 long trips
