Large 8.5 inch X 11 inch Book 50 Mandala images ranging from easy to intricate designs. Only printed on one side per page. Coloring has been proven to reduce stress and promote healing for people of all ages, hence the brand name Coloring For Healing. Mandala Crazy Adult Coloring Book has 50 colouring designs at different levels of difficulty. Pick an easy design for those moments you don't want to spend a lot of time coloring or choose one of the more intricate designs if you have more time. Each design is printed on its own page so there's no need to worry about damaging another Mandala if any ink bleeds through. As with most coloring book pages, your markers may bleed through, so in order to protect the next page, please put another piece of blank paper or card stock behind the page you're coloring.
