Chris and the Gronkowski brothers brought their A game to Shark Tank with their high-quality shaker bottle, Ice Shaker. A-Rod and Mark Cuban were ready to team up to make a deal. The stainless-steel insulated bottles keep drinks cold for hours and won’t spill when vigorously shaken. Ice Shaker was able to go from a one product company to offering an entire line of premium insulated drinkware and is now sold in stores, gyms, and specialty shops across the U.S. #arod #markcuban #gronkowski #gymlif
