Add some jingle to your drumming. This is sized to fit on Vater Fusion model sticks but they should fit anything with a 14.5mm diameter. Each pin compresses to slide on two tambourine jingles and then you can open the pin up to keep the jingles on.

This isn't a permanent percussive accessory due to the plastic pins not being excessively strong but I played with them for a few hours with no problems. If you're a hard hitter your results may vary.
