Yuka Pet EX M size, manufactured by Kainuma Sangyo. UP-203, low and high temperature switchable on both sides. Used for about 3 years after being purchased new. Since it was placed under a mat, there are no stains or odors. There is some dirt from storage. As a bonus, the timer in the image is also included. No claims, no returns. No price reduction, sold as is. Thank you.
