How often do PYO's become available?

Hi turtle_fries and welcome! I guess the easy answer is, whenever there is a batch of pyos to stock! Windstone moved last year and since then, have been dealing with casting issues, like little tiny airholes that show up in the gypsum, especially when painted, so they aren’t getting nearly as many good castings as should be coming out all at once. They are making strides on resolving this issue and are working with a chemist. This most affects smooth sculpts, like dragons. So, only small batches have been showing up in the Windstone online store as they become available. They show up at random though and seemingly fly out of here about as fast as they appear (partly because so many are waiting for them and desperate for blank pyos to paint!)! Once casting is totally settled again and this dreaded ‘dragon pox’ has been cast out, they will probably be more of a regular item in the store and there won’t be a mad rush on them every time they appear. 🙂 I know we are all eagerly awaiting this. *offers a chair and some snacks for the wait*

To add to Siberahk’s comment, before the move, the PYOs were usually stocked pretty consistantly – the only exception being the keeper, but that because the actual mold was torn.
