OKNIFE MBS1 4mm Hex Bit Screwdriver Set, 9 PCS Durable S2 Tool Steel Double-Ended Bit Set with Eternal Pencil, Ideal for Opry, D1, U1 Pro Series and Other 4mm Hex Nut Drivers | 9 PCS Durable S2 Tool Steel Double-Ended Bit Set with Eternal Pencil, T/PH/SL/H sizes, Compatible with 4mm hex drivers

Excellent all good

Work fine. OKNIFE quality although who makes the bits I don't know. All neat and tidy.

Very good 4mm bit set that I use with a Wiha system 4 driver handle and 4mm bit set adapter. They work really well together.

特に鉛筆？ビットは書いた文字も消しゴムで消せるので仕事で書き直しが必要な記入時に重宝しています！

Best pocket set of precision bits that I can find online. They fit well in the back pocket and complement the OKNIFE to be able to do various small electronics and appliance repairs on the fly. I constantly am fixing small equipment like this and find myself grabbing these bits out of my pocket rather than getting much more expensive and fancy precision screwdriver sets from my desk. Worth every penny. I have had absolutely no issues with bits stripping or shearing screws either; fantastic quality.

Tolles kleines Gadget zum erweitern des Tools. Sinnvolle Bits.

価格が高い。品質は期待出来るが、鉛筆？のようなものは書いてもほぼ見えないくらい薄くしか書けません。

Perfect bit set, great addition to my stash pocket. Would highly recommend for EDC (comes with a graphite pencil too). Great companion for the utility knife.
