15 x 22 x 5 cm (approximate measurements) I used this for a little while and then stored it for a while. I'm not planning to use it anymore, so I'm putting it up for sale. Please consider it if you need a lot of them. It's relatively clean, but please understand that it's a used item before purchasing. The price includes shipping, so please refrain from negotiating a discount, even if it's a long shot. When shipping, I will fold it to fit into a dedicated envelope. Thank you for your understanding.
