My buddy and I are pretty stoked at how these came out, they are coming out of the newest molds like this, the fins now come in through underneath, trap and fins have been done just like the Batshop did it.... 10 months of toiling, 6 different molds, I think we are finally there. If you have a minute, take a look at the youtube vid we made showing the trap door snap in.
