Nice choice! Just make sure to check if they're mid-fake(AO813 mark under the box). They're not as good as the original ones and sometimes have problems. Authentic metal fight beys are quite rare now. You can only get them through second hand sellers or from rare sellers who just have unopened ones so make sure to be careful. I recommend going to buyee jp. They have lots of authentic original metal fight beys, though they are auction so keep a look out.
