I do have a couple of problems with them: (1) I have not found a way to actually draw one full ml of liquid - the most I can draw is .75ml, (2) you can see from the photo that the eyedropper does not come anywhere near the bottom of the bottle. They are supposed to be for 30ml bottles and that is what you see in the photo - the seller's eyedropper in a 30ml bottle. You can also see how much liquid is left in the bottle that I could not get the eyedropper to reach. When the liquid got down below the bottom of the eyedropper, I tilted the bottle at an angle and was able to get most of the liquid, but it was a pain. I was making capsules and when it was tilted, it took two draws to get enough liquid and I had to hold the capsule and the bottle at the same time. Not sure if I will keep them or not. ### ⭐⭐ Did NOT fit 1 oz ( 30 ml) bottles *by T***L on Reviewed in the United States on February 10, 2020* These are too long for the 30 ml bottles I have. Probably not allowed to name the brand in the review. I had to order different bottles and spend twice as much. Not happy. ### ⭐⭐⭐⭐⭐ Nicely made with measurement markers *by C***7 on Reviewed in the United States on December 7, 2019* These are great marked droppers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/103915952-premium-vials-1oz-30ml-black-regular-calibrated-measured-marked-dropper](https://www.desertcart.tn/products/103915952-premium-vials-1oz-30ml-black-regular-calibrated-measured-marked-dropper) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-09*
