TOPKEI 15pcs Mini NFC Cards with Storage case Compatible with Fire Emblem:Three Hopes,Three Houses,Engage

These work great! I tested and all of them work/scan. I already scanned them all but I wanted to take a video they do in fact work and scan.

I didnt read up on what we got when scanning these and my eldest says he expected or hoped for something more than an alternate soundtrack for only auxiliary battles.

These cards came super quick. I used them with Fire Emblem Engage. You can scan 5 amiibos per 24 hour period. You get one music and one outfit ticket for each amiibo you scan in Engage.

These work perfectly, are able to be stored in a tiny little case, and as someone with a soft spot for non-cardboard cards (and small ones at that) I love em. Official amiibo cards are actual cardboard which is fragile and flimsy, official amiibos are chunky and take up a ton of space. So these, for me, are vastly superior. Easy recommend. And yes, they all work 100% fine.
