This polish is one of those not-so-beginner-friendly formulas present in some Essie polishes. It's really runny and you need to be careful to have your nails angled slightly downwards as you paint them; the formula is so thin that it will easily flow back and flood your cuticles if your nails are angled upwards. Even with three coats, coverage is a little thin in places and you can see visible nail line if you squint.
Each stud is 5 mm long (3/8") and 3 mm (1/4") wide at the base. I think the photographs on the product page show a slightly smaller stud because I couldn't fit 3 onto one nail as easily as shown on the first design. You can see that one of the three studs on my middle finger is not fully adhered to my nail, as the point of the triangle lifts off the surface of my nail slightly.
How I applied them: I just barely touched the pointed end of an orange stick into some top coat (toothpick also works!) and used that to pick up a stud. With a fresh layer of top coat applied to the nail (not dried yet), I gently placed the stud on to the nail. You'd think the stud would want to stay with the orange stick, but I have such a small amount on the point that it easily affixes to the nail instead. I gently pushed the stud around at the sides with my stick to straighten it out, while also being careful to not press the stud too hard into the polish so it doesn't sink too deeply. I followed up with a second layer of top coat to make sure the studs last. I also tried it without a second top coat layer and one of the studs popped off about a day and a half later. With top coat, they should hold up for several days unless you are pretty rough on your hands/nails. Alternatively, you can apply the studs to a not-yet-dried layer of your base colour and finish with top coat.
Although I wish they were slightly smaller and more delicate, overall I really like the edgy effect of the studs and will be using and re-using them again and again.

Have you used studs or other nail art pieces to up your nail game? I'm looking for some inspiration!
