This is a fantastic accessory pack for your Nintendo Wii. These 'soft & flexible' add-ons bring your sports games to life, and bring you closer to the 'real' game. Each of the four clip-on accessories is made out of high quality foam, which is soft, durable and flexible enabling it to be used safely by both adults and children. Many of the Wii accessories on the market are made out of a hard plastic, which can prove hazardous, so that is why this kit has foam sports extensions.
