Pilot Grandee Chain 0.5 MP for sale
It is twist retract but unlike grandee priere, after twist, it is not a knock and you need to twist again.
I am not aure about the price but I would say, above 200usd would be a correct price. I also accept trading.
I normally don’t like twist mechanisms, but I have two vintage PILOT Grandee pencils that the twist mechanism is very smooth. Nicely done. And it should, for the original purchase price! I’ve seen them priced at ¥5,000, ¥10,000, ¥20,000, and even ¥25,000 (haven’t seen ¥30,000).
