I actually honestly haven't tried the EJ fit (which btw is on 3Dream's website thus not included here) on Judy. I have been using EJ exclusively now. EJ is based on Judy so the fits might work. Would need to try that out though. However, the Eternal Penny fit included here does NOT fit Penny as the head shapes are different. (I've tried that) it could mean that EJ has a different shaped head. But whatever it is, EJ is a definite improvement to Judy. All the toes pose separately ! lol.
