Their numbing cream is one of the best, i bought their 10-day free trial last week because i was going to get a tribal back tattoo and it really works! When i rub it on my skin i thought its bogus but after a few mins i begin to feel numbness on my back.
I was able to get my tube in 7 days as advertised, although they do have overnight shipping also.
I highly recommend dr numb numbing cream to every tattoo artist out there!
