Bring back ridgefiller
You need to make this again, it actually works for a beautiful flat finish for polish and adheres so no chipping . The new infinite shine sucks. Please bring it back

Why, why, why?
The only ridge filler that actually works! Everything else I have tried since this product became unavailable is terrible. My nails crack and split down the middle without this. OPI, please tell us why you stopped selling it. I would have given 5 stars if I could still buy it.

Cracking
Great product my nails have ridges and they split and crack beyond the nail bed at times and this product corrects all my nail issues so sad I can’t find any nail ridge filler or a product that works as good as OPI

I’ve used this ridge filler base polish on my nails, and find it’s the only product that not only smooths the surface for the overcoat color polish, but also makes it last longer. I love it, and hope OPI continues to provide it for consumers!
