Review on 🔵 Cobalt Blue Glass Bottles Droppers for Lab & Scientific Use: Quality and Durability Guaranteed by Aaron Parish

I bought these dropper bottles to store the moisturizing face oil I make for friends and family as Christmas gifts. I love that I can customize products to suit each person's needs. I've included my recipe for a moisturizing face oil below (it's good for dry, mature skin).1. Good quality glass bottles - they don't break if dropped, accidentally of course, but it's good to know.2. The dropper bulbs are not too hard so they are easy to squeeze and absorb the product well.3. Union nuts screw perfectly without a transverse thread - I've tested it several times.4. They don't have any weird chemical smell, which is very important to me since these containers hold facial products. I created a sticker label (Avery): 4 1/4" long and 1 3/4" high. They don't leak when tipped on their side - I tested this with water just to be sure - my sister shakes each gift to try and guess what it is - I had to make sure they didn't leak 2 Ounces of Product 2 Tbsp Argan Oil 2 Tbsp Jojoba Oil 2 Tbsp Rosehip Oil 1 tsp Vitamin E 10 drops Carrot Seed Oil 1 tsp Hyaluronic Acid 10 drops Lavender Essential Oil 10 drops Ylang-Ylang Essential Oil I definitely recommend this product for all the reasons listed above. I bought 4 1/2" x 2" boxes to store my gift dropper bottles - looks very professional and I'm very happy with the result.
