The main characters headgear from The Disastrous Life Of Saiki K, these will needed to be mounted to a headband for cosplay or can be just kept as they are. Using the pole to connect the two other pieces is not recommended, it would be better if you could source some dowel or other material to connect them. The diameters of the holes on the base and ball are 5mm, dowel sanded to 4.7mm will fit snugly and hold them together, the connecting material should be 60mm long. The pole provided is these dimensions and is included for reference.
