Nutshellz cups are the number one choice of professionals that have had their plastic cups fail them. To name a few – Yadier Molina, Fransisco Pena, Caleb Joseph, Yan Gomes, Matt Wieters, Buster Posey, and Kevin Parada. In Hockey Shea Weber and Kerry Price. Our cups wont break when you need them and will protect better than all the rest.
