I've never heard of this site! Awesome huge toy!
I hadn't either until a bird rescue I follow on Instagram posted that MBT donated a bunch of toys to them.
He does quite a bit with cardboard and big balsa pieces which are what Fritz in particular likes. For a long time I thought he didn't like toys, but I was wrong.
He gets tired and frustrated with harder woods or even thick pine pieces. I've found with him he needs like 50% soft woods/cardboard 30% plastic or crunchy/shredding things and 20% hard woods in his cage. He can work on a hard piece for a bit then go destroy some easy stuff and come back to it
@Lady Jane mine too! They already destroyed half of the smaller finger trap toy!
I just bought a bag of 75 for $5 on Amazon
