Pack of 20 colour discs (2 x 10 colours)- The cheapest way to change colour in your saber! See some combos in the product images.
Place these discs on-top of your White LED Module and then your blade on the discs. This will change the colour of your blade depending on your disc combination.
There are 2 of each colour as combining 2 of the same colour can provide a brighter option than a single disc.
