I will also give you the large size Hisonics S Obacom Gel, which is more than half full.

I am selling a Hisonics S ultrasonic device with almost no signs of use. I have many devices in my possession, so I am putting this one up for sale to avoid duplication. I purchased this around mid-last year, but received a replacement early this year and subsequently acquired a similar new product, so I estimate I have used it less than 10 times. It is practically brand new.
