Perfect Keeper Tech Ring

I have been looking for the Perfect Keeper Tech Ring and can not find it in the shop. Is it named something else or found somewhere?

@MikeDClubb it isn't in the game at the moment.

Was looking for it to and a few guides online also said they could not find its equivalent.

There are several rings and food items that are currently not in the NA version because they require harvesting materials from the Ep4 Expeditions.
