Vintage Japanese spring chest expander. Has 5 springs which can be added and removed to adjust tension.

It has wooden handles which rotate on the wire frames, making for a much more practical workout than many others vintage expanders I have seen for sale.

Springs are pretty strong and all 5 of them should ve plenty unless you are already a monster. The springs have a red cord inside that prevent you from overstretching them. In great shape, apart from the finish on the wooden handles.

Thanks for looking!
