This is a JOCHUM pet bottle holder. I am selling it to organize my merchandise. I used it once at a live performance. At that time, it fit the official JO1 penlight perfectly, so I used it as a penlight holder. Since it is a used item, please refrain from purchasing if you are sensitive to such things. Thank you. Instant purchase is OK! I also have other JO1 and JOCHUM items for sale, so please take a look.
