You pull the box out of the Blue Sky machine, and inside is a:

Dusk Potion

Ahaha. First time I've ever vended a potion. :P It isn't worth much but yay it'll help me out with my book buying funds after I sell xD

Wow, I didn't know you could vend potions, congratulations on getting it.

Congratulations! I got a Lilac Potion from a vending machine. I was like 'Woah!' even though it wasn't worth much :P

Well, since many potions stock like other items you can vend them xD That's nice, congrats on that :)

hehe thanks everyone :)

I Thought Potions Were Too Higher Rarity To Vend? o_O

Oh Well, Congratz!

Rare but not impossible. x3 Thanks :P

I've vended several DP's, but I've never vended a potion. Congrats!
