Set of 40 holds each individually labelled with numbers 1 through 40 with arrows pointing to the place where it is the easiest to hold.
#1 to #13 ( green in the photo ) are all really positive jugs.
#14 to #28 ( orange in the photo ) offer some fun challenges but not too crazy.
#29 to #40 ( red in the photo ) offer pinches, slopers, pockets; the whole shebang of training.
Designed for routesetting software for the Treadwall.
