Review on See-Through Cosmetic Container Applicators for Perfect Eyelashes by Kristi Wood

I bought this to apply Careprost on my lashes and brows. This product comes in a tiny bottle and you need to put a drop on the brush and then apply. It's bulky and messy and I felt like I was losing product that way. This empty nail oil stick is a great alternative to applying eyelash serum. The brush is a little bigger than I would like but works well. In fact, it makes applying it to the brow area a breeze! I click twice for one brow, twice for the next, and then one click for each lash. From time to time I wipe the brush with a cotton pad dipped in witch hazel to clean it. One downside was that I couldn't fit the entire contents into the pen even though it's supposed to be 3ml and the Careprost bottle is 3ml. It looks like it's going to be quite difficult to reuse these bottles so I'm not sure I'll try. They're so cheap I'll probably just buy more.
