This shotgun shell fishing bobber is a real blast. It’s a truly unique bobber made from a real 12 gauge shotgun shell and it makes a perfect gift for anyone who likes to hunt or fish. The creators of Shell Bobbers went into the Shark Tank asking for $80k for a 20% share of the company. There were several offers but in the end, Mark reaches a deal for a higher 33% equity. Shell Bobbers are available on Amazon.
