Filler gauge with basic dimensions in thickness but also sub-dimensions to be able to measure more specific dimensions in combination with the basic ones. It stands well in the hand, has a good fit, maybe a little difficult in narrow areas, such as motorcycle cylinder heads, the stem that holds the blades. It requires attention when choosing to measure in combination because the smaller blades have almost imperceptible thickness, so one should not get confused and accidentally "pull" another blade without intending to. They do not easily break, the larger ones have no problem anyway, the smaller ones may struggle. A good and honest product for amateur use.
