Where to buy classic trackpoint cap?

[bugmn]

Hi, I just tried out my first classic cap two months ago and have been using it since. Unfortunately a rather big chunk, about 1/5th of the texture, came off somehow and now that place is just smooth. I'm not a heavy user, about 4 hours/day so I'm not sure how it rubbed out so quick, but I want more

Where can I buy a number of classic ones? I'm not interested in the other two types, only the classic
