Thank you for viewing. This is a set of two "piro-piro" whistles (party blowouts). The plastic packaging is unopened, and the items are new and unused. I purchased these to help my mother strengthen her swallowing function, but the paper tip contains wire, making it a high level of difficulty. It requires a considerable amount of blowing force, so my mother couldn't use them. Perhaps these would be suitable for those undergoing swallowing function training. Size: Approximately 24.2 cm x 2.3 cm Materials: Polypropylene, paper, PET, stainless steel If you wish to purchase multiple sets, please leave a comment. #Speech and Swallowing Function Training #Dysphagia #Swallowing Training #Oral Function Training #Oral Beauty #Frailty Prevention #Nursing Care Rehabilitation #Oral Rehabilitation #Piro-piro Whistle #Toy
