2PM Essentials Frosted Glass Roll On Bottles for Perfume, Wax, Lip Balm, Essential Oils, Deodorant, Frosted Cobalt Blue, 10ml They are very pretty, The color is true cobalt, the matte finish top with two silver lines just makes the bottle more detailed. I am using this bottle to try with a All-Natural Homemade Deodorant Recipe I found online. Grapefruit, Fir Needle, Nutmeg, Lavender, 25-40 drops total. I just make so much to go in the bottle, just to try out. So far the bottle is great and the recipe needs just a little work. So over all it was great project. The bottles did not leak or back when it rolled off the table. They are made with heavy duty glass and are smooth to the touch. The roller is smooth and works great. I received this product at a heavy discount or for free for a honest review.
