Review (5/5): It doesn't leak!!!!
I was impressed with the quality of these bottles. As I use them to mix different infusions of herbal oils, I was concerned that they may leak (we've all had the bottles that leak). These did NOT! The plastic was a good thicker quality, yet I had no problems squeezing the bottle to dispense the oils. I'd recommend these to anyone looking for a leak-proof good quality twist top bottle.
