Get your nails naturally long again with a little help.
This base coat is great for growing out your nails! It works great. Make sure you get a top coat

Excellent adhesion
Great for long lasting gel manicures if your natural nails are flexible. Use as a base coat or a couple of layers plus top coat.

What's the difference with foundation flex and foundation? Foundation flex is more $$
Not sure what the difference is in the foundation flex and regular foundation. But will hopefully wear better and last longer.

Does it’s job exactly as expected - Would recommend
There’s absolutely nothing wrong with this flexible rubber base for gel nails. I bought this, because I had already been using a rubber base plus fiber glass to add strength to my fine brittle nails. Unfortunately, that other product was so difficult to remove. I figured getting one without fiberglass would make for easier removal, and I was right. This flexible base coat does provide more strength than plain gel polishes, but it’s not nearly as strong as the other rubber plus fiberglass product. This foundation flex performed well. I would recommend this brand if your nails aren’t as brittle as mine; the flexibility allows for some minor bending and easier removal. No weird texture. Suitable stickiness. Perfectly clear. Good product.

No lifting after 3 weeks!
I purchased the foundation flex to help strengthen my natural nails and it's amazing! I did apply the pro bond acid free primer prior to applying and so far I have zero lift. It also cured perfectly under the LED lamp in 90 seconds. Great product!

Best gel base coat ever used
This is the best gel base I’ve ever used, I’ve tried many brands, bluesy, Amelie all kinds and never found one that performed so well, only a builder gel has had the same lasting power but that involves quite a lot of faffing around to build the apex, this is easy. Picture is day ten, my gels usually last a few weeks but with some chipping on the tips, I am day ten and not one single chip! I used a primer, this base, a Victoria vynn gel colour and the gel ish top it off top coat.
