This lot of funnels is rather expensive but it is actually very practical: stacking allows good storage and there is no overflow with their ingenious design. Little Red is finely grooved on the outside which allows air to pass and thus no spillage of the liquid is possible (loccurrence, oil). Gray means serves for salt, spices and even powdered sugar, no overflow to date. I do not use much big but I really like the other two and they would miss me if I would do without it.
