Abdominal breathing long Piro Piro, unopened, unused, brand new. You can easily do long breaths with 10 breaths a day (approximate). The secret is the special ultra-long Piro Piro that stretches up to about 1 meter. Simply blowing it supports abdominal breathing by making you conscious of your abdomen. To add more resistance, it contains three wires, and both blowing and returning help to improve the effects of abdominal breathing. Also, there are markings in four stages, so it's a simple exercise just by blowing according to the stage of the marking.
