I use a grooming box from Decathlon - ?15, has shelves for small stuff like bands, needles, tape, tags, ropes, gloves. Then a bigger interior for applicators, iodine, sprays, calcium, antibiotics, slip gel, drenches, lamb boost stuff. You can carry it by hand, attach a shoulder strap, and sit on it. Also tall enough to put diagonally in a corner, to shield a lamb while you kneel on it and work on the lamb. Plastic, so easy to wash, disinfect and reload at the end of the lambing season ( I have 6, my lambing season is short - if there was more, you can do it more frequently) and if you put it in water by accident, it doesn't matter.
