Fine ~ [SEP] I've used this glue in the past several times and its always worked okay for me. Defiantly not for someone with thinner hair, and make sure to follow through with the heat application. Not sure that I'd recommend getting it from this specific seller. The plastic was broken open on the one I purchased from them which wasn't exactly thrilling with any sort of cosmetic or beauty product. I contacted the seller but the declined to do anything about it so whatever just a waste.
