The button machines from American, but machines are excellent! Sturdy and stable. They put up With heavy use. And since we let the young people build the machine, under guidance, They are not always gentle with it. But I never worry about the machine having any issues. Their button sets are also fabulous. You have to be very careful to only get one piece of plastic or the button won’t seal properly, but attention to detail is always important and building anything so that’s not a negative in my opinion. We do events where we build buttons each month and we have had kids come back wearing the buttons from months ago, so I know that they stand up to, preteens and teenagers, dragging them all over the world.
