Sku is: 6932162502037 and I have attached a receipt scan.
While admittedly flimsy plastic, they are simple to install and the soft close is a nice, usually high priced feature.
The product is not available only online as far as I can find, but worth a look if you're already at the store and need toilet seats.
There were at least 4 of each at the Cleveland Ave. Location in Westerville / Columbus Ohio
