H - grommets for tattoo machines are basic equipment for every tattoo artist who uses standard tattoo needles with regular tattoo machines. These rubber bands in the shape of the letter ""H"" are mounted on the small hammer of the machine and then a needle with an eye is fitted on the rubber.

This kind of rubber band is made of soft rubber for better needle attachment to the small hammer, and makes impacts softer.

These rubber bands are not designed for Cheyenne Hawk rotary tattoo machines or similar ones.
