This ceramic tile coaster is printed with image of my original textile artwork of 3 koi fishes swimming in koi pond with lotus/waterlily flowers & lily pads.Koi fish symbolize good fortune, prosperity & longevity. Lotus flower symbolize purity, beauty, grace & strength. Using these tiles will help to attract those positive energy to wherever they are displayed.The tile size is 4.25" x 4.25". Satin Finish. There are felt bumpers on the back of the tile.The tiles can be cleaned by hand with sponges, but do not use harsh things like steel wool. Do NOT scratch or cut on the top of the tiles.Besides using the tiles as coasters, they also can be used as decorative tiles on the indoor wall like kitchen or bathroom when doing tiling or remodeling project. Just remove the bumpers before tiling.
