Del Sol Polishs are Toluene, DBP and Formaldehyde free.
The color I got is a newer shade called Spring Thaw, which is a pretty blue based silver that turns blue based mid-tone purple under sunlight in 30 seconds. It took three coats to coats to cover my nails and stop streaking. The top coat is designed to let UV rays through to the nail color. The top coat has a REALLY strong nail polish smell. It took about about 3 minutes to dry.
The polish lasted 6 days, I had some tiny cracks on after 5 days, then if started peeling on the 6 days. It was a little difficult to remove.
