With its smooth gradient tones in green and its soft matte finish, the Calvin's Green Gradient 3x3x3 Cube (Stickerless) is an eye-catching take on the traditional puzzle. Perfect for casual solves or exhibition, each cube has a single colorway and a faint shading effect that gives it a clean, minimalist look. The smooth and pleasurable turning makes it a terrific gift or collector's piece, even though it's not designed for speedcubing. It is a must-have for lovers of designer twisty puzzles because of its distinctive appearance and distinctive Calvin's Puzzle logo.
