Ian, had these been Palitoys I may have been inclined to use words not often heard in civil company; but they're Kenner, so you're golden
I happen to love these. I think they are absolutely awesome. I do acknowledge that it is deeply frowned upon and understand why (and inside I am weeping about the GDE Vader) but I really, really like them. I couldn't bring myself to do it except, perhaps, on reseals (or modern, but just not the same) but I would happily buy them if already done.
And anyway, after we're dust (along with most POTF bubbles), who's to say there won't be a new technique to gently remove the ink if the next owner wishes?
