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

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.

This multi tool set is a must have. It works with the otacle and with the oknife u1 pro. Have it on a key ring with a carabiner and it helps with glasses and knives and any small screws. It also comes with a pencil bit which you can buy refill bits from amazon or olight directly. Lightweight super durable bits. Small storage footprint and excellent value.

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！

Tolles kleines Gadget zum erweitern des Tools. Sinnvolle Bits.

This is exactly what I wanted to add to my edc! Quality bits that are easily carried.

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。
