This is a simple small case for a couple of taps and a handle that I sourced individually in a local hardware store.

My set includes:
- Yato YT-2995 (M1-M8 Wrench)
- Yato YT-44840 (M3 Tap)
- Yato YT-44841 (M4 Tap)
- Yato YT-44842 (M5 Tap)
- Yato YT-44843 (M6 Tap)

You may be able to use differently sized taps too, but I can only guarantee these will fit.
