Note About Flowchucks

While the modular system enables us to create an illuminated prop resembling nunchaku, these are not traditional nunchaku. They are a toy designed for object manipulation and play, not a weapon. Regardless, the legality of nunchaku is questionable in some states - please check local regulations before purchasing.

Modular System Features

  • you can quickly remove your flowlights and flowcaps and use them in poi, martial props and our full range of staffs
  • save money and experiment with all sorts of different props and styles of flow
  • you can connect 2 or more flowlights instantly by simply snapping the nose of one into another's tail
  • flowtoys tubes are made of polycarbonate, the most durable clear plastic available and the same material used for bulletproof glasses, and are available in a variety of lengths to suit your personal style and needs


While the tubes are technically 1"OD and 7/8"ID, we have our tubing custom extruded to ensure that it meets our specs, as the difference of 5/1000ths of an inch can mean that the tubing is too tight or too loose! All the tubing is prepped in-house, which involves size-testing, cutting the tubing down, punching holes and deburring the edges and blowing off all the shavings and dust for a smooth, clean finish. All the jigs and many of the tools were developed and made in-house.

    Terrific flow prop!

    I've had these for a couple years now and have brought them to music festivals, burns, and even a 5k glow race with an afterparty. You get a lot of attention quickly and they're a blast to wield. The cord length comes in a little short so wrist rolls can sometimes be more difficult than necessary but that's a nitpick, and you can change the cord length yourself. Can't recommend these enough!

    Love these things!

    Got a pair for Christmas and I am super stoked, I like the concept and after some use, I feel comfortable that it is a reliable prop. Simple to operate with lots of great colors and light changes. I need a second one!
