Bondhus Hex Driver Beefier and Grippier Handle/Sleeve

I have a Bondhus hex driver set. The smallest drivers (e.g. 1.5mm and 2mm) have EXTREMELY tiny handles. I have a very hard time getting any torque on them at all because I can only grip it with my fingertips. These sleeve/handles slide over the top of the existing ones and give you a surface that is nice and beefy. You can actually grip it with your full hand and start cranking it as hard as you want. You feel me?

These should fit any Bondhus driver handle that is about 10.8mm across -- see the pic that includes the calipers.
