Square Root crafts the ultimate lemon-lime refreshment with their 1UP Mix. They combine Sicilian lemon juice, Mexican lime juice, sugar, and Maldon sea salt for a fruity isotonic hit that's perfect after a long day. Each pack comes with a limited edition letterpress sleeve made on a 1960s printing machine—a collectible piece of retro charm. Square Root's squeezy pouch pays homage to classic soda-verse flavours, letting you mix 10 drinks your way with ice and a splash of soda. Simple, refreshing, and with a nostalgic twist.
