a question about too faced e/s

[yumemiru]

this is prob in the wrong thread forum, so mods, please move it if it's wrongly place, thanks.

so i just bought their e/s today and i was wondering what's with the case inside moving, it can be taken out. I mean it's megnitized so it can be replace with refill or something? I'm so confused why it's this way.
thanks girls for your opinion.
