This is a set of 9 hex keys. I obtained it at KOHNAN about 7-8 years ago, but I haven't used it much, so it's clean with no dirt or damage. I will wrap it securely in cushioning material and ship it via Nekopos. - Set contents: 9 pieces (TT10, TT15, TT20, TT25, TT27, TT30, TT40, TT45, TT50) - Model number: LFX-20-244 - Color: Silver Thank you for looking.
