### ⭐⭐⭐⭐⭐ とにかく書きやすい
*by V***O on May 17, 2025*

このペンはとにかく書きやすい。こればっかり使ってる。

### ⭐⭐⭐⭐⭐ 夜注文し翌午前中に届きました。
*by 松***輔 on May 17, 2025*

世界一黒いインクということで、主に仕事用として使用しており確かに他のインクと比べ黒く、ボールの滑りも滑らかでお気に入りのペンです。昨日インク残量を確認したところ残りわずかでしたので夜22時過ぎに注文。翌日の午前中には商品がポストに届いておりました。Amazon凄すぎ！

### ⭐⭐⭐⭐ 使い道考えてなかった
*by カ***－ on July 21, 2024*

多色のボールペンで、安いので買ったのですが、あまり手帳のデコはしないので、活用方法を模索中です。書き心地は良いです。
