Jetstream Refill Compatibility Guide: SXR vs SXR-80 / SXR-L80
This is exactly the kind of stationery problem BeeLife can solve well: the pen says JETSTREAM on the barrel, but that still does not tell you which refill fits.
The word JETSTREAM is not a refill code. Match the body to the exact SXR family.
Mitsubishi Pencil's official refill database separates full-size single-pen refills such as SXR-5 from slimmer multi-pen families such as SXR-80 and SXR-L80.
BeeLife compatibility rule
Start with the body model. A common SXN-150 single pen is listed for SXR-38, SXR-5, SXR-7 and SXR-10 families, while many 3-color and 4&1 bodies are listed with slimmer SXR-80 / SXR-L80 refills.
Official compatibility includes SXR-38 / 5 / 7 / 10.
Used by many Jetstream multi-function bodies.
Do not buy by ink name alone.
Single-pen Jetstream
Mitsubishi Pencil lists SXR-38, SXR-5, SXR-7 and SXR-10 as compatible with the SXN-150 family, corresponding to 0.38, 0.5, 0.7 and 1.0mm.
Multi-pen Jetstream
The official database separately lists SXR-80 and newer SXR-L80 families for bodies such as Jetstream 3-color and 4&1 models. These slim refills are not something to guess from the outer pen shape.
I would screenshot the pen's model code before ordering refills. “Jetstream 0.5 black” still leaves room for the wrong physical refill format.

Bottom line
Jetstream compatibility is easy once you treat the body model and refill family as a pair.
