Meso Therapy Needles MB 30G - 0.29x4mm thin-walled Meso Needles from Medical Brokers are characterized primarily by significantly thinner tube walls compared to standard needles available on the market. This results in a larger inner diameter of the needle compared to a standard needle of the same size. The difference, depending on the size, is from 12% to 30%. Furthermore, the correct angle of the tip increases the sharpness of the Meso Needles.
