Lately I've seen a couple of Sailor Pro Gear Slim pens not part of the usual catalog of pens. I found a robin's egg blue from Morita's store in Osaka, and another in a bright pink marked "Bungbox" with a clover on the finial, that looks like a Sailor. These seem to be made specially for certain stores in Japan. I'm wondering how many more of these might be out there. Are any of you aware of others I may be missing? Thank you for your help and advice!
