A trophy that fits in your pocket. This is not a mere keychain; it is a Tipo tennis ball, permanently preserved in its prime, forever unburdened by felt, pressure, or the indignity of a double fault. Let it dangle from your keys as a quiet, stylish reminder of the game you love, or the game you aspire to love on weekends. Choose your hue. Green for the classicist, pink for the iconoclast. The only bounce it provides is to your aesthetic.
