Shagbuilts “The One” is the big brother of the D20. An optimized slide system and a motor upgrade make the “The One” just like the Beast Mode version of the D20. So if you are looking for real power and maximum efficiency, your search is over. “The one” and only ShagBuilt! A Swiss precision motor with dual ball bearings handles big jobs providing more torque than the d20. More torque means it can deliver the same consistent punch at lower speeds as well as handle bigger needle groupings. The aluminum body has a 4.7oz lightweight design with great balance that’s easy on the wrist, only .1 oz heavier than the d20 but with the same great balance. The Shagbuilt THE ONE Tattoo Machine works with all rotary ready power supplies.
