This is a great first time toy or for someone who wants something super slim and small. Popsicle is 3.4" (8.5 cm) in length and 0.73" (1.8 cm) in diameter. It has a soft polyurethane coating over ABS plastic. There are 7 vibration settings. Popsicle uses 1 AAA battery, so no searching for special batteries. This vibe is splash-proof.
