These are classic sierra styled twist pen kits, called the Pro as they have a premium quality Taiwanese twist mechanism in the heel of the pen.
Unlike standard sierra kits that twist near the nib and rotate between your tube and the mechanism this could cause damage to your turned parts.
Our kits twist by turning the finial end and only the kit parts themselves touch when rotating.
Replacement of the refill in these kits can be done in 2 ways - unscrewing the finial end or unscrewing the nib section - you'll never have a jammed refill again.
Our starter pack consists of 1 pen kit of your choice with a 10.5mm drill bit and Sierra Pro bushing set
