While my brother was on vacation in Aruba he purchased me this colour changing (when exposed to sunlight) nail polish by "Del Sol." I'm always out to try new nail polishes & as soon as I received it I had to try it out. This colour changes from a pink (no sunlight) to purple (sunlight). The colour is absolutely gorgeous. To get an opaque finish, at least 3 coats are necessary, since it is slightly sheer. A great first-time try nail polish & lovely for the summer. Wonderful job, Del Sol!
