Review: Great, but if I could change one thing - I’ve purchased numerous times on desertcart and in person and it works great. One piece of criticism is that once you open it, it tends to dry out in the cap, which can be difficult to get out. I do wish there was a way to remove it easier so that way the needle cap can continue to be used but overall there is no odor consistency is great and it dries like a rubber which is exactly what I’m looking for.
