Trying to find an old pen

Hi! Trying to remember the name of an old pen brand that was in production around the early 2000s or so.

Was a stubby mini pen? that you could pull apart somewhat to have the insert popout to write with.

The grip was kinda triangular, and came with a clip that would attach to a keychain.

Appoligies if this is the wrong place but this has been annoying me trying to find this and I have been failing.
