 Hi, I'm Sandrine and I'm head educator and test coordinator at Pro Nails. Today I'm very happy to show you our new base shells. So here there are the three Pro Nails base shells. There are curable only 30 seconds in the light, two minutes in UV and there are low heat sensations and you can work five fingers at the same time. So welcome to the base clear, the base pink and the base perfect. The base clear, it has a medium viscosity which is perfect for students and beginning nail technicians. It offers a perfect adhesion to normal to dry and strong nail types and it's really easy to use. Now the base pink, it's the soft pink version of the base clear. It also has a medium viscosity which will not run into the cuticles and will offer a perfect adhesion to normal to dry nails. This one is truly the base to make a beautiful French manicure look. Here is my favorite, the base perfect. It has a very runny viscosity, suitable for more experienced nail technician. It offers an extreme adhesion to all nail types even the very thin greasy and damaged nails. The base perfect is the perfect base for all problem nails. Here are the results on the natural nails. The base clear is totally transparent. The base pink has a slight covering effect with the touch of baby pink and the base perfect is totally transparent and very thin. Have fun choosing and using your products, bye!
