Korea's Pargu is very active in the vintage kyosho field and it's always a pleasure to stumble upon a new item of his on ebay. This time it's the red shock collar for Optima, you know, the one that breaks easily when you overscrew it. He says it's handmade but what does it mean exactly? Just wondering... Anyway, it's way tougher than the originals, I guess, and if he succeeds to make some of them, it will probably be a huge win for him (and for us optimaniacs).
I don't post a link here but every optimaniac should know how to check it out :D
