How rare do players loot the Music Box?

I've being farming for weeks so far nothing. But I still got 30 more years to live. I'm at age 40 estimated age period is 70 years to live...so you think I'll be able to get the Music Box before I die?

what music box?

Im equally none the wiser about this

Oh wait, is this one of those extremely rare pof cache/chest drops?

I never knew these music boxes existed, but I must now try to acquire them.

There's a number of music box items, which can be looted from chests in PoF maps. I have no idea how rare they are, but they can't be very common since they're not well known. Unfortunately they're also account bound on acquire so you can't get them any other way.

probably like chak egg sac rare, maybe?

The fact they're not openly advertised adds to their rarity, as few are actually Aware that they're a thing, so few actually farm them.
