Frisbee
One Frisbee, two versions. The 25-cm transparent one lights up completely, while the 22.5-cm black one has a brightly colored rim. Both are waterproof and rechargeable via USB-C. This makes throwing in the dark a lot more fun, because you can see it coming.
Accessories
Vests, goal lights, and spare bulbs.
A Frisbee that glows
A Frisbee that you can track in the dark. The LEDs are embedded in the rim, and the colors cycle around it. The transparent version lasts up to two hours on a single charge, while the black version lasts 45 minutes. The transparent version is slightly larger and glows across its entire surface, while the black version is a bit smaller and glows more brightly along the rim.
It's waterproof (IP67), so wet grass or a sudden shower aren't a problem. Just don't take it in the pool.
