Just wanted to share about the Go Tubbs containers that I bought from Amazon recently.
(I'm not affiliated with the maker, I just wanted to review them.)
As I have two trips of two weeks each , coming up this year; I tested the containers for how many days product they would hold, before I travel.
I bought the very smallest round ones, 15 ml size, three in a set, each about one inch by one inch, with the squeeze- on lids.
I put face cream in one, toothpaste in the second, and hair putty/styling cream in the other.
I got 15 days of toothpaste use, brushing three times per day.
I got 14 days of face cream use, using twice a day.
Three weeks later, I've only used half the hair product, though I do have very short hair.
So I love them, as they take up hardly any room at all!
Would recommend them for the carry-on packers, as they will give you more room in your liquids bag.
On the other hand, I don't like the Go Tubes bottles at all.
Always looking for teeny containers!
