I found these coasters in the gift shop of the Immersive Van Gogh Exhibit when it visited Minneapolis, and after using them, I wished I had purchased more. I found "RainCaper" on the back of the coasters, so I was able to find the RainCaper website to add to my collection. My favorite coasters are the irises, blossoms, and poppies and daisies. They are gorgeous, and, especially when not in use, they add small touches of beauty on table tops and other surfaces they adorn. They also absorb moisture well and leave no telltale mark. HIghly recommend. They make lovely gifts.
