Review (4/5): Closes firmly, somewhat squeezable, tall and narrow
This set of bottles come in a six-pack with blue, green, purple, pink, and two clear. They're fairly standard plastic travel-bottles; they squeeze but they're just a little bit thin and brittle in your fingers. If you want something that will stand up to serious compression, you'll have to look at the more expensive bottles with a more rubberized texture.
The pull spout is a good one; there's a ridge inside that holds it closed, and it takes some significant effort to pull it open. This could actually be a drawback for someone without a strong grip, but it does ensure the bottle won't leak easily and I like the feature. It will wear down over time, but I expect it to last a few years at least which is about as much as you can ask for this price, and the whole lit screws off for refilling and cleaning.
I would have given these five stars, except that the current image is not very accurate. The bottles are taller than it looks in the picture. That was fine for me, since the tall narrow shape fits perfectly with the rest of my travel bottles, but other buyers should be aware that these are about five inches tall.
