I recently pulled these from my 5 string. These are in the black case which has a slightly different look (better, I think) from what is pictured on the website. The measurements are 4-3/16 x 1-3/8" (104mm x 34mm). These go for $320/pr on the q-tuner website - was asking $200 shipped in the lower 48. Now taking offers (no trades though). Sorry for the poor pictures.
