My wife is a large animal veterinarian, who spends the majority of her days doing farm visits. She was always complaining about the disorganisation in the back of her van and how she could never find anything. With her help, I designed and build her this veterinary cabinet and we installed it in the back of her car.
All drawers are subdivided to exact measurements of her equipment, medicine bottles etc.
Now 3 years later she still claims it is the best money she has ever spent and it is saving her time every single day!
