The Jetstreat RT (known as the Jetstream Rubber Body in Japan) is a variant of the Uni Jetstream Standard ballpoint pen. The pens both use the SXR refill, but the RT has thicker body with a rubbery grip along the entire outer surface.
The RT also has metal components — namely the front cone piece and the clip. The top button looks to be metal but is actually plastic.
The RT BLX series is part of the RT series. The name is a result of the blended colors the RTX pens use, like blue black, red black, and green black.
