on the subeta wiki.... is states that you can get a Monthly Collection item.... have anyone ever got one and how would you know if you have gotten one?

I think there's a very, very rare chance of vending one, but it's usually just an item, not the box itself.

Generally Monthly Collections are sold in the Cash Shop, like the July 2013 Collection that is for this month. Each Collection contains ~10 different items from which you can choose one.

so there is chance that i have one... i have vending alot and everything is in my shop now

If you're talking about the vending machines I think they only give out the older items. Like, I've gotten and Also in 6 years those are the only ones I've ever gotten so... yeah, really small chance.

You'd know because the item's rarity would say 'Collection Item'.

i dont think it said collection item LOL thank you
