This is a 19cm My Scale from SUNSTAR stationery. It's a Showa-era retro item. It was unopened, but I opened it for the photos. It comes with cute, mini set squares. Regarding the My Scale's features... Functionality is combined with fun in this beautiful ruler made of styrene resin. And more, as written on the instruction sheet, so please take a look at the photos. This item has been stored at home for a long time, so there are many small scratches. Please refrain from purchasing if you are concerned about this. The original plastic bag has deteriorated considerably, so I will put it in a new OPP bag and ship it via Nekopos.
