This Set of 8 adult coloring rocks is a great group activity, a relaxing & meditative outlet for your inner creativity or a thoughtful gift. They are suitable for leaving as kindness rocks for others to find, for use as decorative accentuate around the home & garden or as a finished decorative gift. The zentangle style patterns are hand drawn on hand casted plaster & cement stones. This makes them uniformly round in shape & gives them a great surfaces for coloring with paint pens, which are included. I will include a random selection of colors in the 4 or 12 paint pen options. The Paint pens are premium quality & can be used for many projects after you are done painting your rocks. There is a boxed set of colors if you order 8 pens. See photos for pen images.Your order will include a variety of patterns & not necessarily the exact ones pictured. Rocks are approximately 2 1/2" in diameter. My rocks are hand painted with attention to detail. But, because each rock is individually hand crafted, no two will ever be exactly alike. Rocks that are made to order & can be closely replicated as picture shows. I can also create a custom theme such as hearts, shamrocks, butterflies, etc. Just message me with custom requests. Instructions for finishing & sealing stones are included. Colored stones are not included & are pictured only as illustration. Gel pens may not be exactly the same ones pictured depending on my ability to source them.
