Nintendo Labo: cardboard stable?

I wanted to ask how stable the cardboard and the individual parts are in nintendo labo.

Difficult to describe but I try it: Very stable cardboard.

So it's still cardboard, it can't be so incredibly stable, but because it is cardboard and how thin it is, it can withstand a lot. If you use Nintendo Labo fairly normally, you shouldn't worry that something will break quickly

How long does the cardboard last?

It all depends on how much you use them. Can't give any specific information now, except that it is sufficiently durable.
