Review on INSFIT Toiletries Containers Squeezable Accessories by Lacey Rinehart

*Highly* Recommended! I can see how they can leak if you don't put the flip top cap on properly when you close it, or the cap isn't screwed on tight (there's also a space between the bottle and the screw cap that goes over it where water from the shower can pool) . Just make sure you *completely dry* around the opening and inside the lid before you close it. The liquid remaining between the cap/cap/neck of the bottle acts as a lubricant that prevents hermetic sealing. / or Atmospheric pressure on flexible silicone containers while driving may cause leakage. Things with alcohol or acetone, such as B. hand sanitizer and nail polish remover, especially when overcrowded, because they expand with increased cabin pressure. I carry travel size hand sanitizer or separate wipes/packets of sanitizer and/or nail polish remover and leave a regular sized bottle at home - or is it cheap enough to buy at destination and leave what I don't use. The holdall is heavy and well made which serves as an extra precaution but nothing spilled inside.
