The iconic circular barbell offered here from 10g through to the impressively large 00g
Both balls are removable so custom ball sizes are an option.
Balls are sold singularly and two threaded balls in the matching gauge are needed to complete this piece in 10g, 8g, and 6g.
Balls are available here.
4g, 2g, 0g, and 00g are sold complete with the standard balls for the gauge and diameter.
Spare or replacement threaded balls for ALL gauges are available here.
