DreamSipper Tongue Training Device for Snoring and Swallowing Issues Retail Price: ¥3,891 (tax included) Purchased on Amazon. This is a listing for the DreamSipper, a tongue training device that supports the improvement of snoring and swallowing function. It can be used to help with snoring while sleeping, improve difficulty swallowing, and for oral muscle training. I used it a couple of times (2-3 times) to try it out, but I've decided to use a different device as my main one, so I'm listing this one. After use, I have carefully cleaned and disinfected it, and I will ship it in a clean condition, so please rest assured. There are no noticeable scratches or stains, and the condition is good. *I can add information about the presence or absence of the outer box and accessories if needed. If you were interested in this, please give it a try. Instant purchase is OK, and feel free to ask about price reductions!
