Air-Tite JBP3004 JBP 30 G x 5/32 in. (4 mm) Ultra-thin Wall NanoneedleUltra thin needles designed to reduce patient discomfort, minimize hematomas and limit swelling. Using a special process called Micron Sharpness, ultra thin walled needles aim to allow injection of higher viscosity solutions through a smaller entry to reduce pain and bleeding. Goal is to minimize the surface area so injectors have minimal impact on soft tissue and more satisfied patients.
