detail of the website comment regarding the material "Tolex"
"I used a tough, synthetic covering called "Tolex", which is used to cover Rock band amplifiers, speakers, and just about every musical instrument case in existence from Rock guitars to French Horns. Its usually plain black, but I was able to purchase this red/black Python-skin look stuff from a speaker supply house."
