Hi Venice,

My ben-wa balls are joined up with string on which there's a little loop to pull them out, but either way, it's not likely you wouldn't be able to get them out, either through (as albear says) gravity, or just um, a little push.

There's some stuff on ben-wa balls (types and their removal) here on another thread, the ben-wa stuff starts roughly around post 4.

Hope this helps.
