The add-on shaders come in three different sizes. These can be easily recognised as they have the top section completely removed. This tool is to be applied after any main shader when using the Colour Placement System.
The add-on shaders are sold in a set which contains all of the following sizes (total of 15 units).
- 5 x add-on shaders size 3 = 120mm diameter
- 5 x add-on shaders size 4 = 140mm diameter
- 5 x add-on shaders size 5 = 150mm diameter
