FULL SET (sizes 1-28) – Contains 14 double sided tools ranging from 0.5mm to 15mm in diameter. The sizes are incremental to allow a larger selection of dots and to allow for more designs. These sizes create circles from 0.2 to 0.7 inches (0.5mm to 18mm). DESIGNED FOR EVERYONE – These very light weighted tools fit perfectly into the hand, so they are suitable for those with arthritis, or with limited hand movements. No experience or practise is needed to use the tools or to create mandala designs. They have been used from schools to retirement homes. NUMBERED – Each tool is numbered to help pattern creation EASY TO CLEAN – Simply wipe with a paper towel, after each use. For built up paint, simply dip into freshly boiled water for 10 seconds. Use a cream cleanser to remove any stains (use sparingly). Avoid using alcohol or solvents to clean, as these will crack the tools over time. RELAXING – When you create perfect dots, users can instantly enjoy the dotting experience. Benefits include increased relaxation, anxiety reducing, increased focus and unleashing your hidden creativity.
