I have bought items from her before, but it looks like her store is not operating again until October.
Because I am in the UK I have used these sellers instead :

But they are a little more expensive than Kay's.
There were some in this australian store I was eyeing up a while back, but they may be a bit too fancy for what you need:

Good luck!
