This is the hose for the Re-Hair Dryer PET by Re-Beau Do. The hose tends to loosen with use, and you can tighten the bellows to make it firm. However, it was a hassle to do that during grooming, so I bought a spare and used two hoses. But, I got used to the process and can now use one hose normally, so I'm selling the extra hose. It's in good working condition with no damage. (For packaging, the hose is loosened (made thicker and shorter). Please tighten the bellows to a suitable firmness when using.) Re-Beau Do
