Transistor is a modular shelf designed by Barberini & Gunnell for the brand Tonelli, with glass sectional modules, available in clear or extra-clear glass finish, and aluminium joint. Transistor is the modular library with infinite possibilities. As in its principal electronic function, where it takes inspiration from, transistor gathers data and multiplies its contents magnifying them, thus the Tonelli Design library is able to “compose” and “multiply” itself, without end. The shelf is made in clear or extra clear glass with joints in anodized aluminium.
