LabStockScience Purchase Boston Round Bottles, 4 oz. (Pack of 12)

These bottles are great. I make my own skin products (toners, wash, serums,etc) and these were perfect for all of them. I needed this dark container to prolong the lifespan of my products and prevent oxidation. Everything arrived intact and perfectly fine, and that's great considering that I live on the opposite side of the world.The bottle itself is a little on the heavy side since it's made of glass but this wasn't an issue even if I use them while in the shower. I really like the cone-shaped thing on the cap, it helps prevent excess drips/residues from liquid that usually gets stuck in the cap when you open the bottle. I'm not sure if that's its real purpose tho.It doesn't leak at all even if I shake it vigorously. I use it for my apple cider vinegar toner as well and shake it before use and no spills! (I hate the smell of vinegar so the no spillage is a 10-star for me)I was previously using amber plastic bottles from another brand but they keep getting deformed after some time. It's even more difficult to use liquids that were heated since it melted the plastic. There are 12 of these and given that they're so sturdy, it would probably last me a long time!

I purchased the Boston Round Bottles, 4 Oz Pack of 12 from Never Pay Retail Again, Inc. They are perfect, exactly as described. Packaged in a suitable cardboard box with small cardboard separators, the black caps were enclosed in a plastic zip lock bag placed inside the sealed box. This was all put into a larger shipping box, cushioned with air pillows. Each cap fit securely atop a bottle, the seal is secure. All parts are new and clean and fragrance free. They allow additional space for a 4 ounce fill, so they are excellent for my needs. I've ordered another box of bottles from this company who ships extremely quickly.

The bottles were packaged really well when they arrived, lots of bubble wrap (the bottles are glass after all). When I opened the package though, I noticed a couple of the plastic lids were broken, despite the great packaging (probably need better packaging in the corners). I contacted the seller though, to see if I could just order some replacement lids, and they contacted me back the same day to tell me that replacements were already on there way! I got the new lids very quickly and everything is great!The glass bottles are pretty standard, and are very sturdy. The lids were also surprisingly good, very thick and sturdy plastic, and they were the nicer lids, that instead of a cheap paper insert seal, it was a high quality, erosion resistant, Black Phenolic Lid with Polycone Liner plastic seal (in a kind of cone shape).I'm using these bottle to make vanilla extract in, I've already purchased the beans and vodka, and the bottles were really easy to clean, the mouth was wide enough to perfectly fit my kitchen funnel. 4oz bottles of homemade vanilla extract, a perfect gift!I would highly recommend this product! Great customer service!

I used these to make extracts. First vanilla and cinnamon, then some home remedies like elderberry tincture. They hold slightly more than 4 ounces, so you have room to shake mixtures if necessary. The lids are secure and lined. I wound up decanting the extracts into smaller bottles for gifts, but this is what's in my kitchen cabinet!. They arrived well packaged, the product box inside an Amazon box with bubble wrap. None of the bottles were broken, and I've dropped several on our hardwood floors without issue, though they are glass and I should be more careful.These would also be perfect for flavoring syrups for coffee or homemade soda!

In the past two years LabStock changed the caps of the bottles. They used to have molded rubber/plastic inside the cap. This gave a soft and tight seal. Now it is just a round circle of cardboard inside the cap. It is cheaper and not as great a seal. The quality was great. Now it is good/acceptable.At least LabStock dropped the price from $10.50-$11 (2017) to $9.50-$10 (2019).The packaging is good - well-thought out and protects the bottles during shipping.The bottles themselves are a strong choice. The size, durability, color and price are worth it.Size - perfect for making extracts at home.Durability - pretty strong and similar to higher-end extract bottles found in stores.Color - The brown protects contents from the sun.Price - The price in 2017 and 2019 are fine. I prefer paying a dollar more for a better cap/bottle. It is still less than $1/bottle.

I am starting a large project of making herbal extracts and needed bottles NOW. Originally I had ordered from another company, but after many empty weeks I gave up and tried this company. My bottles arrived in two days flat. The packaging was superb. Instead of reams of land fill clogging bubble wrap, they were fitted into heavy duty divided cartons with the lids separately packed on top in a plastic bag. In addition, the cartons were then placed inside an outer box. It would have been impossible for them to have been damaged. The bottles themselves are made of high quality glass. They are professional grade; nary a flaw or ripple in the bunch. I couldn't be more pleased. They will make my homemade product look as first rate as any from a large manufacturer. The company also followed up the delivery with an email checking to make sure I was satisfied, and when a small glitch did occur with Amazon, they actually got on the telephone and went to bat for me. I am a customer for life! This is a great company with a great product that they sell for a great price! You just can't beat that combination!
