Kotori4Lyfe provided really good details on this so I just want to add that I personally got my Kingblade from amazon for only $30 usd and it can be programmed to have a variety of colors and people have created a QR specifically intended to replicate the Aqours official blades. If you're interested and end up using it I could help you with any problems you have! https://www.amazon.com/gp/product/B015E0NEAI/ref=ya_st_dp_summary?ie=UTF8&psc=1
