STAR TREK TRANSPORTER PAD LED COASTERS 4PC SET

Until a future comes in which condensation no longer exists, coasters will be a useful device. These is a set of 4 coasters that look and sound like Star Trek: The Original Series transporter pads. Yes, we said "sound." When you place a drink on one or remove it, the coaster lights up and plays either a materialization or a dematerialization sound. (Lights turn off after 10 seconds to preserve batteries.) If it's all a little too overwhelming, you can set it just to light up. But that's basically only half the fun. Each coaster requires 2 CR2032 button cell batteries (not included).
