### ⭐⭐⭐⭐⭐ 非常にスムーズ
*by ロ***ン on May 18, 2021*

スムーズで耐水性も高い。サイン用のボールペン

### ⭐⭐⭐⭐⭐ キレイな青です
*by A***R on February 3, 2020*

いいですね、CROSSのリフィルは。 とてもスムーズな書き心地だし、色もキレイです。

### ⭐⭐⭐⭐ 替芯に当たり外れがあるとは...
*by 趣***し on September 20, 2014*

２本の替芯を買いました。 １本目は、インクがちゃんと出て、滑らか且つスラスラと何とも書き心地が良い。 しかしながら、２本目は新品にもかかわらずかすれまくりで使い物にならなかった。 当たりが2本中1本だったので☆を１つ減らしました。ちゃんとインクが出れば、素晴らしい一品です。
