Its that new invisible wood Rich, you gotta get up to date on all this new stuff! HeHeHe, Looks great, nice job beafing up all the stiles to really stand out. Are you going to do an addition on top of these that will go to the ceiling or just keep carboys on top. I think either displaying a few up right on top or doing some standard racks on top would really make it top notch, a few differnt designs all in one really pops!!!!!!!!!!
