Vintage Rotary Fabric Cutter 

Model RTY-1  

Package is taped as if it's been opened.

OLFA

Spare Blades RB28-2 

2 packages

1 is taped as if it's been opened. .It's hard to tell if there are 2 blades in the package or just one.

ALSO, THESE BLADE SPARES SAY THEY ARE FOR THE RTY-1/G Model. So I am not sure if they are compatible with the cutter.

Made in Japan
