I would buy a couple packs of a 100 if I was sure they were from TY, but I’m sure you have all heard about the fake TY disks circulating around online. Shop4tech is selling them for $149 for a 100 pack. Do you have any reason to believe they are actually TY and not just TY coded?
I have the Tayio Yudens from www.rima.com - in my hands - and they are NOT fake -
Rima DOES NOT DEAL IN FAKES!!! and are to be trusted - they cannot afford to deal in fakes 'cause their business loss from this board alone would be in the multi-thousands of dollars!!
Buy from Rima with confidence-
