I just read a GREAT review by Canadian Nail Fanatic on using alternative brands for nail stamping aside from using the expensive Konad special nail polish (which I have never used as it is too expensive for me).
Surprisingly enough the one she preferred aside from the Konad was the brand I use which is Kleancolor. I love using the Kleancolor brand for any stamping I do, as a result of that I probably have about 18 Kleancolor colors. The Sheer Lilac is a lovely color to use when stamping.
Here is the Kleancolor Sheer Lilac:
She had also mentioned Wet n' Wild brand, which I really do not like for stamping. Whenever I use it it tends to peel and not stick to the nail properly and I end up having to use and orange stick to tap it down. She mentioned as well, how faint it was as a black polish, I also had this issue and using the Kleancolor was amazing to me when I switched.
Anyway enough of my rambling, I will post the review link below.
