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.

M3 x 6mm | steel | socket head | hex drive (2.5mm) | 6mm length | M3-0.5 Metric Coarse Threads

Modular System Features

  • you can quickly remove your capsule lights 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 capsule lights using a capsule link for tubing-based props
  • 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.

    So glad that I purchased these flowchucks!

    So glad that I purchased these flowchucks! They make spinning nunchucks Soo much more enjoyable! When at a festival or flow jam they stand out and make an awesome statement! They definitely stand out from all the poi and staff spinners with a look and flow all their own! They trump all other nunchuck set ups hands down. Perfectly weighted. Brilliant colors that are customizable! The lifetime warrantee is key. When buying such a top line prop you want to make sure your getting everything that your looking for. The durability and quality are matched by their excellent customer service!! Couldn't ask for more. Such a great investment! I thought the fact that the lights being 2 separate pods in each handle was a disadvantage, but it looks super great when it comes to putting on a show. They also look way better in regards to trails then 1 solid bar when it comes to long exposure photos.

    I love my flowchucks.

    I love my flowchucks. They are my trusted companion when it comes to LED shows. There is a multitude of color options that allow me to play with color combinations and dazzle others long into the night. I love how durable and bright they are as well. Wonderful, wonderful product by wonderful people. I have an in depth review of them here:
    Many color modes to select from.
    Easy to charge.
    Stands up to my high velocity bounce style.
    Many inspiring nights with this. When you spin this, people will definitely notice.
    With four capsules, you have a ridiculous amount of color combinations to choose from!

    Very bright and long lasting battery life

    Prompt delivery and friendly customer service. These flowchucks are durable and well designed. Very bright and long lasting battery life. Loads of fun and completely customizable. I was pleased with the product and would order from flowtoys again. Easy to assemble. These chucks are guaranteed to attract attention and wow spectators. Unlike most nunchucks that cause a disturbance in public places due to being a dangerous weapon. These seem to be pyblicly accepted. I have performed with these in store parking lots and on the street with no complications with law enforcement. Decent weight and comfortable size. Heavy enough to simulate oak and chain yet light enough to not cause significant injuries if accidentally hit by them
