This is the best price we've seen on this ducky night light. It's made out of resin, not rubber, which makes it better for a light if not an actual rubber duck, but it's a nice homage to our beloved rubber duckies. The light has an easily replaceable 7 watt bulb and an on/off switch. The duck is detachable for cleaning.
