A coaster that i designed according to Daddy's needs. There are 6x 8mm slots at the bottom to add rubber sticky things (8mm) so that it does not move around and stays in place (see last picture). Here is a link to the rubber i used.https://www.amazon.se/dp/B0BFHGF1ND?psc=1&ref=ppx_yo2ov_dt_b_product_details Here is a link from amazon.comhttps://www.amazon.com/LLRY-Adhesive-Dampening-Furniture-Diameter/dp/B07G86DL1L/ref=sr_1_5_mod_primary_new?crid=30Z18057NK6A7&dib=eyJ2IjoiMSJ9.aZN8Tl7O3N4SqI
