small grooma groomer,
soft brush, medium brush and two hard brushes,
metal curry to clean brushes,
curved, handled, hard rubber scraper,
wide toothed comb and mane and tail brush,
several hoof picks color coded to the horse if they have thrush which are disinfected after use before returning to the tote,
a zippered tote that is easy to carry over the shoulder or in hand as well as having a strap that has a clip for hanging,
inside the house or in a cool dry location in a rubber maid container I keep the following:
several rolls of vet wrap, gauze and soft cotton, wound powder, iodine scrub and solution, nolvasan, cortisone, anti bac cream, anti fungal, sulfadene, bag balm, ivory soap, eye safe saline solution, rx meds for emergencies, different sizes of squirt bottles and a couple of spray bottles, syringes and needles in different sizes, scissors, knife with both flat and one with serrated blade, gloves, coconut oil, orvis paste, vicks baby rub. I do keep specialty shampoos for the dogs that enhance color or clean white and if I need use those on the horses. When I showed on a regular basis I had a completely different set up and products for specific things that related to cleaning.
ETA I am sure there is more in either place than listed but right off the top of my head I can't remember which means I bought it and probably wasn't impressed.
