The only seam to be found is where the rubber meets the metal, making that the obvious entry point.

Optimistically, we blast it with some heat in order to soften the adhesive which, presumably, holds this thing together. Then we attach two perfectly-fitting suction cups, one to either side, and start tug-of-warring.

The white cover material on the charging surface starts to stretch slightly, but the actual gap doesn’t budge. (Sometimes we're too optimistic.)

So, under the knife it goes! Some persuasion from our razor knife gets us past the white cover, between the plastic and metal underneath, where we can start prying.
