closes firmly somewhat squeezable tall and narrow [SEP] this set of bottles come in a six pack with blue green purple pink and two clear they are fairly standard plastic travel bottles they squeeze but they are just a little bit thin and brittle in your fingers if you want something that will stand up to serious compression you will have to look at the more expensive bottles with a more rubberized texturethe pull spout is a good one there is 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 will not 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 cleaningi 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
