I bought Avery 28877 Clean Edge Business Card paper and put my NFC Stickers on back and they work great. I used the templet on the Avery website and print 10 cards at a time. Look great and sturdy. I keep them all in a Business card holder for easy access.
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
