What makes some yoyos so expensive?

The axiom in my opinion is a “bargin meateal” a metal yoyo that is kinda cheap (even though it isnt that cheep) and the main reason that i think this is because i tried my friends axiom and some of the orange paint came off onto the string (the string was white so it was extra noticable) Now the 888 on the other hand is awesome, light, durble,balenced and they have hubstacs SO DONT GET FOOLED
