We absolutely love these GoToob Travel Bottles.
We started using these bottles about a couple years ago and we’ve been pretty pleased with the results. They fit very nicely in your 3-1-1 liquids bag. Each one is also easy to fill and refill. Just unscrew the cap and fill. We also appreciate the “textured” surface which keeps them from slipping out of our hands when using them in places like the shower.
Don’t be put off by the flexibility of these bottles. The caps really do stay on and we’ve never had one leak. Each bottle has a handy suction cup attached. It’s great in small bathrooms when counter space is at a premium. Just suction it to the bathroom mirror and you’re good to go. The bottles are available in 1.25 oz, 2 oz and 3oz sizes as well as a variety of colors. Because of their unique shape, you can fit a few more into that 3-1-1 bag than ordinary sized bottles.
The only drawback to the GoToob bottles is with very thick liquids, like some shampoos or sun tan lotions. If you decide at some point in the future to put something else in the same bottle, it can be a bit difficult to clean.
