This sure looks like an amazing “little” implant!
Neat!!
Harder but doable.
If the artist knows what he is doing, should be fine for a needle pocket install (with one of those 5mm needles)
That, if feasible with the LF antenna perks (not to say pricks) would be a reeeeally usefull implant.
Although I see it much more likely for someone to just encase 2 xSeries blinkies with some polymer just to keep them as a single implant.
In which case I would probably just want a couple of regular xSeries…
