Made by Oka, known for toilet seat covers, toilet seat cushions, bath mats, and more. This is a toilet seat cushion with a three-dimensional (3D) design that can be wiped clean even when wet. Due to the special material (polyethylene foam), it doesn't feel cold when you sit on it, even in winter, making it popular as an energy-saving toilet cushion. It was a bit expensive for a toilet seat cushion, but I bought several replacements. However, the existing ones are still in good condition because they are more durable than I expected, so I am selling them in my year-end clear-out. For those who know the product and are willing to use Eco-Mercari shipping, thank you in advance.
