These Jungle Cock subs we have been working on a couple of years now. The hard part was to find the way to lazer cut theme so they would be very thind in the "stem" just like a nautral feather, and we found the way :-) They are made of one layer very strong fabric and are moving very well in the water. They vill never split in 2 We made them in 4 size, and packed them with 48 eyes in each pack. .
