?Warm Reminder?: Due to low temperature, the base coat may be clumpy or get thick. If you find this, please contact us, we will provide after-sales service to your satisfaction. Tip: No need to wipe the base coat's tacky residue off. This will help the color coat stay on your nail longer. ? What You Will Get?: 1*7.3ml Base Coat+ 1*7.3ml Top Coat. Great Gift Idea. It is normal for a base coat and color gel to remain a little sticky after curing, which will make a better adhesion between nails and gel layers. No worry about that. The top coat would seal it. (Please do not over-cured it or it would peel off easily). ?LED/UV Lamp Required?:The gel top coat and base coat need to be cured under LED/UV lamps. Different power nail lamps have different curing times. Please extend or shorten the curing time according to the power of the nail lamps you use. ?Long-Lasting for 28 Days?: Gel Nail Polish Base and Top Coat can make your gel last for over 28 days with proper application due to its wear resistant feature. The flexible top coat makes your nails glossy shine and avoids nicks, chips and smudges. ?Healthy Base and Top Coat?: 9 Toxin-Free Ingredients make it healthy and low odor. No harsh ingredients or adhesives lead to damaged nails. With proper application, last at least 3 weeks.
