THE INViSIBLE NEEDLE is the first needle of its kind and the thinnest needle available to date.
Technology advancements have made it possible to make this needle 33% thinner than a 30G needle (used for insulin syringes) and 14% thinner than the TSK 33G needle.
This extremely small diameter of THE INViSIBLE NEEDLE results in a near painless experience for patients and is ideal for BoNT injections.
The Low Dead Space hub is designed to reduce the effective space left behind in the needle hub as close to zero. This new patented LDS hub design results in savings of up to 0.08ml of product.
