Each set is custom made to fit your hand. This little guide will cover sizing, how to measure, and of course you may also contact me with any questions you may have. If this is giving you too much of a hard time, you can order a sizing kit for three dollars (sizing kits are optional, not a necessity)In the chart below you can see the sizes. For example, if from thumb to pinky you measure 2,5,4,6,9 you are size small. if you do not see your size under "set sizes" just choose "Custom" size and include your sizes at checkout. Enchanted by Monice cannot be held responsible if your nails do not fit. The sizes you provide will be used, so please measure correctly
