Is it “okay” to customize a perfectly mint 3rd gen pony?
Most customizers (myself included) think it’s okay since 3rd generation ponies are widely available and really not worth a lot right now. For $5 or even less when they’re on sale, that will barely buy you a drink at Starbucks! However, you want to check the value of your 3rd gen pony before you rip it apart, since some of them have become “rare”.
