Getting the weight of your poi handles optimized is an important step to making your poi feel just right :)

If you'd like to add weight to your knob handles we offer knob washer kits in both 6mm, and 11mm inner diameter that will perfectly fit into your handles. These come with washers that enable you to customize the weight of your handles.


Washers come in 3 different inner diameters (ID) to accommodate different leash thicknesses, and 3 different outer diameters (OD) to accommodate different knobs:

  • ID/6mm: compatible with flowcord, phatty, smithy and paracord
  • ID/10mm: compatible with FPC
  • ID/11mm: compatible with static rope
  • OD/19-20mm: compatible with play and pom knobs
