DropperStop 1/2 oz Amber Glass Dropper Bottles (15mL) with Tapered Glass Droppers - Pack of 12

I ordered these specifically for storing small batches of a DIY GHK-Cu cosmetic serum, and they have worked perfectly for that purpose. The amber glass is useful for ingredients that are better protected from light, and the 15mL size is ideal for making manageable batches without keeping a large container open for an extended period. The tapered glass droppers have worked smoothly and make it easy to dispense a controlled amount without pouring too much or making a mess. The bottles also arrived intact, clean, and packaged well enough that none were chipped or broken. The caps thread on securely, and I have not noticed any leaking during normal upright storage. Having twelve bottles in the pack also gives me plenty for future batches, testing different formulations, or labeling and organizing them separately. Overall, these are simple, well-made amber dropper bottles that worked exactly as expected for my DIY cosmetic-serum project.

These DropperStop 1/2 oz Amber Glass Dropper Bottles work terrific when making up Neat essential oil blends that will be diluted into other containers - the dropper then allows specific number of drops to be used. I appreciated the durability of it. The bottles are brown amber glass which is great to store essential oils - or any oils. It is advertised for 1/2 oz or 15 mL volume and it works well for my Neat oils blends for storage volume. The price is worth it.

Great for traveling. Bottles don’t leak and size perfect for serums.

These worked perfect for my facial serums. Used on a 14 day trip and lasted the entire time. Small but held enough for the entire time. I think if you tighten the top too much it causes the squeeze top to lift and leak a bit. Otherwise they were perfect. I have multiple sizes.

These were wrapped safely, arrived on time. I was a little nervouse because they came in a paper type package and these are glass. But none were broken, but I think that was luck. I like they had lids on the bottles, not in a seperate package, and not tight either.

These were a gift to a friend who makes tinctures, and he thought they worked well for his purpose. I was also the beneficiary of some of his tinctures, so my impression is that they seal well, and the dropper works well to measure how much tincture you want to use. The dark glass of the bottles serves well to preserve the quality of the tincture, as well. Would buy again for such use.

Nice and sleek. The Amber is not as dark as I thought it would be for the product I make.

I’m really happy with the quality of these right out of the gate. They’re a nice thick glass that feels like quality, and they’re a good size too. All of them arrived with zero damage whatsoever. I use these for tinctures and i sometimes take them with me, these definitely seem sturdy enough for that. They haven’t leaked either, and i usually shake them up pretty well.
