Boston Round Bottles, 1/2 Oz Pack of 12

Great bottles! The glass is thick, the seams are smooth, the threads are better than most pop bottles, and there is a nice big flat for the seal to seat. The caps seem quite sturdy, they fit nicely, and have some sort of teflon-looking seal, which will make them good for pretty much anything you want to store. On the underside "15ml" is clearly stamped along with "YB" and a 3 digit number.I have not used them yet, but so far they seem good.

Lids are equally as important. These have the poly-seal caps which help prevent from leakage. Perfect for my needs.

These 15ml bottles are just what I needed for transporting smaller amounts of essential oils and are perfect for trying out new blends.So far, I've not had any issues with caps leaking, and amber glass is of good quality.Bottles arrived quickly and were very well packaged. I won't hesitate to purchase from this seller again.

I ordered these to put small doses of herbs in. For those who have asked if they need to be washed first, PLEASE wash them. I opened each one to check to make sure that each was ok and some sort of (what appeared to be plastic) particles fell out of 4 or 5 of the 12 bottles. I took a photo. No biggie because I always wash the bottles before using them but, just be aware. In addition, when I filled a bowl and rinsed them out in the bowl, the water was pretty nasty looking. The lids also seem to stick when they are about half way on but then if you gently "push past" that point, it does seem to tighten the whole way. They seem like decent bottles.. as described but please wash them. I'm not quite sure what the debris was inside them. There is no odor. I have not filled them yet since I won't need them for about another 2 months but wanted to warn other to WASH THEM FIRST

First of all the bottles are dark to help preserve it's contents and a perfect size to carry in your pocket or purse. They seal very well and are very solid over all. A quick reference for size would be slightly thicker than a thumb and as long as the second joint of your thumb to the tip.I use them to carry Habanero and green chili powder, I'm sure you can find a ton of other spices you can carry, for instance Montreal steak seasoning, sea salt, no sodium seasoning or low calorie additive. Big or sticky herbs will not work IMO, Such as fresh Basil or parsleyI just print out a label from my Dymo address label printer and cover with a piece of tape to make the printing on the label lasts longer.The bottle does not come with a shaker top (It's too small for that) or a spoon in the top. I just tilt and tap the top to dispense, you might have to tap into your palm on some free flowing products like salt in order to not over do it.I bought some small funnels in order to fill these bottles, it will save your sanity in short order.

I am using these to store homeopathic remedies. I need the amber color and I need the glass container. If you use them for this then boil the bottles but not the caps. The plastic insert in the cap which seals it does not like boiling water and will lift off. It is not the end of the world but it does require fitting them all back again once the water cools.

These are great little bottles and the price couldn't be beat! I would definitely order them again!

Many of the reviews here mentioned a rubber seal. When I ordered, they did not come with one. So I contacted the merchant, and was told to return them as defective. But they no longer come with the rubber seal. That was the entire reason why I purchased them. I give this 3 stars because if you don't need the seal, then they seem to be good bottles.
