Check some of the dept stores or stationery shops. At one point Rotring disappeared for a while, company was bought over and production resumed.

Note: I do have the Rotring 500 for sale 

That would be me. But the Rotring sold out already.

Why do you like the Rotring 300 so much? I rarely hear other people talk about the 300 model.

i think the kuru toga you're referring to is the roulette version. gonna get mine in a few days. so excited
and the roulette looks like a rotring, thus influenced my choice of model purchase

basically the high end one (and more expensive) are the roulette and the the high grade. the difference between these two are the rubber grip VS knurled metal grip of the grip part. the body part are still plastic unfortunately

anything that's better than your everyday buncho leads lol. if they sell in bundles, even better since they don't come cheap

any shops in KL that sell those?
well it is dirt cheap and the quantity is twice of the pilot. not to mention longer. too bad it's 2B. easy to break
