The Flashflight Jr. has a softer rubber than the regular Flashflight disc and a push-botton on/off switch rather than a dial. They are great for the little ones because they are easier to catch and fly about 3/4 the distance as a regular frisbee. Flashflight Jrs weigh 110g, are 8.5" in diameter and come with easy-to-replace batteries (2-DL2016) that last over 25 luminous hours in the Disc-O Flashflight Jr which lights up and slowly morphs through the colors red - green - blue - orange - purple - teal - white.
