Tumble down the rabbit hole and add these trippy patterns to your platter. Guaranteed to turn your table into a portal to another dimension. When spinning at 33 or 45 rpm, this design produces a shimmering and surprisingly colorful effect. A dark red color along the lines in between each circle might also appear. The spinning circles might look like they are expanding or shrinking. After watching the effect for a little bit, you might get a little dizzy when you look away. When rinsing, flickering shadowy images should race around the inner circles. The faster you rinse, the faster they move. If you rinse very slowly, the circles might even start to look 3D! These slipmats are specially made using "sublimation printing," which ensures that felt surface does not leave any dye residue that could wear on your records.
