Bondhus balldriver set is constructed of black hardend steel shafts with red durable plastic handles.
The "ProHold" Tip has a small nipple on the ball to hold the screw on the end.
This package includes,
One 1.5mm balldriver
One 2mm balldriver
One 2.5mm balldriver
One 3mm balldriver
One 4mm balldriver
One 5mm balldriver
The Prohold tip is great for working with those small RC-size screws.
Although some of the larger screwdrivers will go unused, the ones I am using are holding up great.
