Having a hard time with the sizing instructions? Don't worry your pretty little head, I've got you covered! This Sizing Kit comes with 10 blank nails of your shape of choice! Each nail is each size I offer in my sets, so you can hold them to your nail and submit your sizes to me. Note: This kit is completely optional, and not needed to get your sizes. Check my sizing guide located on each product page, and under the tab "sizing" for more on sizing yourself at home without the kit.
