This kit is slightly cheaper since the parts are all generic colored. If you want more specific or special things (UV, GiTD, LED, ect) you'll have to buy the parts individually. We do not offer substitutions or alterations to any of the pieces/parts that are included with this kit.
Fits up to a 24" head with padding on the inside. This head will fit glasses. This head does experience some symmetry issues, and we have it on our list of things to be remodeled.
