ミニマルマグネットブックマーク

I was worried it might slip out, but at just 4g it stays perfectly in place without adding any bulk to my book. The magnetic closure keeps both sides aligned neatly, even when I toss the book in my bag.

The magnet is surprisingly strong for such a slim piece, so it doesn't slip off even in my bag. At only 4g, I forget it's even in my book until I need it.

Stays perfectly in place on my page corners without sliding off, which is rare for such a thin bookmark. The 4g weight makes it feel barely there in my bag.
