This is a leather case specifically for Kaweco Sport pens. It costs around 2500 yen when new. The condition is almost the same as new. There is some bulging, but this is because a Kaweco Sport pen was stored inside for six months, leaving an impression. Since it's a case for Kaweco Sport pens, there shouldn't be any problems. The item has never been used, only purchased new and stored with a pen inside. It's in extremely beautiful condition. Thank you.
