Mighty flea questions

I am planning to get a flea soon,what do they ship with,I know so far:
mighty flea(duh)
and 2 strings for fleas

what else?

Come in a velvet pouch.

In a cool vending machine ball thing…

That is it.

I thought it came with a few strings,and I’m wondering about a spere axle.

Yes - It also comes with a spare axle.

Why do they give you 2 axles? easy to break it?

Keep it spinning™

Because its so tiny its easy to sit on. Also the axle is smaller then usual, so sitting on it might break it.
