the use of double-sided adhesive:first clean the surface of your nails, because the surface of the nails will secrete oil to affect the stickiness of the double-sided adhesive., find the double glue that corresponds to your fingernail size, then stick to your fingernail, tear off the sticker above, take the front end of the fake nail, press the back end of the fake nail and the root of the nail for about 5 seconds, and try not to touch the ornaments on the fake nail for about 5 seconds, or else the ornaments will be knocked off!you can also paste the double-sided adhesive directly to the back of the fake nail, and then to its nail root, press down, but this method I tried, I think it is not very good, because when you take off the fake nails, the colloid will remain on the fake nail, the next use, so I suggest that you first paste the glue on its own. On the nails.because thumb and two fingers will often be active, so we suggest that you can attach 2 double-sided adhesive on thumb and two fingers.Specification:as shown in the picture, transparent colorSize:as shown in the figureQuantity:5pcs/24 Stickers, 10pcs/24 StickersNotePlease allow 1-3cm differs due to manual measurement.Due to the different display and different light, the picture may not reflect the actual color of the item.
