If you want to clean it or warm it properly, then you have to remove vibration part, you can push/pull insert part through case, but you can't really put it back this way. It's really thin, you will need oily lube. You wiil get some water-based stuff, but it's not what you want. Hot water can warm it properly, but it doesn't stay warm for too long, not rly that easy to use, if you want to enjoy it...
