STEP 1 - A Perfect Fit Kit ( Nail Sizing Kit)! »A Sizing Kit is REQUIRED for all first time customers. Why? Sizing Kits are the BEST way to achieve a truly custom & most perfect fit for you as evryone’s nail shape and sizes are different. This step will ensure the longevity of your wear and the most natural looking nails possible. Want to order your nails and sizing kit together? You CAN and we RECOMMEND ! Simply add a sizing kit to your nail order and you will receive your sizing kit first and FREE! That’s right, if you order nails with your sizing kit for your first order your sizing kit is FREE! Once you’ve submitted your sizes to AppaLuxe and I will begin working on your nail set(s). Plus you only pay shipping once with this option, so it’s a Win-win! »Each Shape & Length require their own sizing kits as they are not interchangeable. So if you are not a first time customer but desire to change your nail shape &/or length at any time you will need to purchase a new sizing kit in that option. Or you can request a complimentary sizing kit in the new shape/length when you purchase a set of nails.
