Balls of Steel are literally just as the name would suggest, premium drink coolers made from stainless steel balls, designed to chill your whiskey.
Designed by Matthew Geddie, Balls of Steel operate much like the Whiskey Stones we have featured in the past. Simply freeze the balls, carefully place them in your glass already filled with whiskey, roll the ball and back and forth, and you’re ready to drink. The balls themselves are crafted from a high stainless steel metal that is not only non-toxic, but it will also not alter the flavor your whiskey in any way. When you’re not using your Balls of Steel, you can store them in the velvet sack included with the balls. The best part is that a percentage of all the profits generated are donated to support research of testicular cancer. See it in action below and purchase your own from Amazon.
