Meso Needles MB 31G - 0.25x4mm thin-walled Meso Needles from Medical Brokers are primarily characterized 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, ranges from 12 to 30%. Additionally, the correct angle of the tip enhances the sharpness of the Meso Needles.
