Easily one of our most highly demanded yo-yos! The Mighty Flea has the same diameter as a US quarter… that’s right, a quarter! The best apart the Mighty Flea is that it is a serious modern performance yo-yo. To keep the weight of the Flea at an acceptable level for modern play, we manufactured the body out of steel. Then, we brought in custom flea size response pads, a flea size axle, and a high quality flea size ball bearing.
