LATE PRODUCTION NEW BOXED SETS WITH DAMAGED BOXES!! 12" / 10" SUPER Power-Trig Slide Rule A few random boxed sets have belt loops, just luck of the draw! Every set inspected and checked by us before shipment. These boxed sets have box cover creases, the odd tear, some box water stains, various other scrapes and shelf wear. The sets are perfect inside, but sadly, the boxes are not. Grab a great bargain while we have them! Some have minimal box trauma (we are pretty critical), we will ship the best first. Just ask yourself, how good would I look after sitting on a leaky warehouse shelf for 40 years? Take a big SALE discount for the damaged box! (20 Scales !!)
