The ACME P900 European Length Refill is a rebranded Schmidt P900 Parker Style G2 ballpoint refill. It has a collar near the tip and a rear cap that allow the refill to be used in any pen that takes a standard ceramic (European, international, safety) rollerball (RB) refill. By taking the collar and rear cap off, the refill can be used in any pen that takes a Parker Style G2 refill. This refill is available in black, blue, red, magenta, green, turquoise, and purple ink. No third party refill makers offer a substitute for this refill, although there are numerous Parker Style G2 refills on the market.
