New in box Toilet Timer. The Toilet Timer by KATAMCO is a product just released and their label preparation is amazing. It's not actually restricting time one spends in the restroom but it's a sand timer with the sand passing through like an hourglass, just it's not an hour glass. That's right potty humor at it's finest and it times out at five minutes. To get the humor just right for this product, they have printed up durable stickers to cover the face of the design, to give it the effect with custom shapes punched out at just the right spot. Katamco Toilet Timer Classic and Toilet Timer Dad Bundle, Funny Gift for Men, Husband, Dad, Birthday, Christmas, Stocking Stuffer. As seen on Shark Tank.
