This is a tip compatible with shaping machines from Reeds 'n Stuff and Hertenberger. The model number is "VARC". It's generally considered a medium size, falling between the standard 39 and the wider 25. It allows for breath support without making it difficult to find the correct pitch, making it very comfortable to play. Please refer to the third photo for the following sizes (units: mm): 0…7.11 10…7 24…5.8 34…4.23 total…76 I bought about 50 of these, but I ended up going back to the tips I was using before, so I'm selling these as I haven't used them in a long time. Made of steel, so it wears less than brass, allowing for stable manufacturing. Current retail price: 25,900 yen (refer to Oboe shop) The average price in specialist shops in Japan seems to be 28,000-30,000 yen.
