Louis Erard x Konstantin Chaykin Unfrogettable Purple
Once upon a time… No, this is once upon a twist. Louis Erard and Konstantin Chaykin are back, to flip the script, twist traditions and leap over conventions with a grin. Yes, it really jumps out at you. Introducing the Unfrogettable. A Frog Princess like you’ve never seen before. Born of Slavic myth, suited in samurai armor, built in the Swiss Jura. A fully reworked case. A regulator turned creature. A spell you can wear. Powered by Chaykin’s ingenious mind and Louis Erard’s rebellious spirit. The result? Something no one asked for, but no one will forget. Beyond the fun, precision. Beyond the madness, mastery.
