Review: 一回落とすと必ず割れると評判のgalaxy Z fold6を使うなら頑丈なカバーが欠かせない。 悪い点 ・ごつい。せっかくメーカーが頑張って薄型化したのに台無し。 ・背面ディスプレイの透明カバー越しだとタッチパネルの感度が悪くなる。 良い点 ・装着して広げるとペンホルダー部が中央の出っ張りとなり、持ちやすい。 ・落としても大丈夫そうな安心感がある。 総合的にはかなり満足。
Review: ゴツく使い手を選ぶケースではあるのだが、、、結構な高さから落としてしまってケースは破損したのに本体には全く影響なく守れたので安心してつかえますよ。 なので2つ目を今使用しています。

ゴツく使い手を選ぶケースではあるのだが、、、結構な高さから落としてしまってケースは破損したのに本体には全く影響なく守れたので安心してつかえますよ。 なので2つ目を今使用しています。

性能というか、得に形状とか問題はないんですが、Sペンは別売りですか？付属品ですか？
