Review (5/5): I ordered these because of the good reviews, and I am impressed with them
I ordered these because of the good reviews, and I am impressed with them. I filled them today with some perfume I made and the oil doesn't leak. The quality is great, dark amber is great for helping to avoid spoiling of natural products. The roller ball is stainless steel and feels nice against your skin (especially on a super hot day!). It was a little difficult to press into the bottle, but if you use a towel to avoid hurting your hand its fine. (It is a good thing because it means airtight!) I am in the process of testing formulations and containers for products I will be selling in my business, and will definitely use these. Great price too!
