Great base coat works well to put on under your OPI nail polish.
Great base coat to put your polish on top of also helps extend the life of your polish. OPI is a great nail polish, will last a long time even on Natural Nails if applied properly.

My Go-To Natural Nail Base Coat for the Last 20+ Years
OPI has been my go-to polish brand for the last 20+ years. OPI products are always consistent, high quality, and long lasting in terms of wear. I have natural nails, so OPI’s Natural Nail Base Coat is a solid pick for my nails. This is the only base coat I’ve found that applies evenly and dries rapidly without any micro bubbles. Paired with an eye-catching OPI Nail Lacquer and the OG OPI Top Coat makes for a spectacular natural-nail manicure! The length and width of the brush is just right and very easy to work with, it’s one of the things I like about OPI products. Lastly, I do suggest ordering a replacement bottle around the half-way mark. It can begin to become harder to evenly coat the brush leading to brush marks and other issues. The product I received was fresh, authentic, and top-quality. Pro Tip: NEVER expose to heat. It will ensure the next manicure is full of micro bubbling and orange peel.

Stay on.
This is pretty good product. Make sure your nails, shiny and protect them for a few days.

Stronger Nails Fast
It goes on in a smooth, even coat, dries almost instantly, and gives your nails a clean, natural sheen. With a few uses, they feel thicker and sturdier, with far less bending or breakage. Color polish chips less because the base is stronger, but it also works well on its own when you want a simple, healthy look. It has quite average nail polish smell.

Versatile but not as strong
Thin layer that works well as base and top coat. I feel like it chips easier than other top coats I have used. I keep this in my travel bag for quick touch ups.

Did not fail
Love it! Opi nail base coat goes on easy and stays on for about a week. Protected my soft nails from shredding and breaking. Helps with hardening the nail.

best product on the market. Excellent for weak and soft nails. I have tried other products but nothing to compare to this fantastic product. The price is reasonable as well.

I just tried this product for the first time, and I am really pleased with it. It was quick drying and produced a good coverage, and nice shine,. So far I am just using it as a clear polish without any coloured polish. It also claims to be a nail hardener, and that is what I am using it for. And so far it seems to be working. I have found that you can't go wrong using any OPI product. I definitely recommend this product.
