This is an airbrush, compressor, or other airbrush related accessories for modeling use.
Here's a fine single-action airbrush with a no-needle paint delivery system. The 0.3mm nozzle allows for versatile painting. Set includes the all-metal airbrush, 18cc bottle (Gunze's Mr. Color Aqueous bottles fit right on, too), air valve, air hose joint, wrench, and 102cm air hose, plus an extra color cup pipe. Includes a manual in both Japanese and English.
