Schutt White Plastic Mini Helmet Chinstrap Buckles/Pins Combo. Add these plastic buckles/pins to your Riddell Mini Helmet to give it an added touch of authenticity. Or replace a lost buckle from your Schutt Mini Helmet's chinstrap. Buckles come exactly as pictured. The mounting pins are molded into the buckle. The pins are slightly too big if you try to use on a Riddell Mini Helmet. You will need to increase the size of the hole if using on a Riddell Mini Helmet.
