TAPIO Speedy Clipper Blade Set for Clippers, 4 Pieces (1, 2, 3, 5mm)

Purchased and used as educational material for vocational school about 13 years ago.
Since then, it has been used about twice a year.
The 2mm and 3mm blades were confirmed to be in working condition at the end of last year, but the 1mm and 5mm blades have lost their sharpness and require sharpening. (Sharpening is also recommended for the 2mm and 3mm blades due to prolonged use.)
The 2mm blade has rust on it (see 3rd image).
All four blades have engraved numbers from their time at vocational school (see 4th image).
The item will be shipped in its original blade protection case (see 5th image).
It will be shipped via postal mail.
Individual sales are also possible, so please comment if interested.

Please understand that this is a used item stored at home before purchasing.
Please refrain from purchasing if you are sensitive about such matters.
Returns after arrival are not accepted.
