The design and size of the hair clip we wish to purchase can be chosen from your current stock designs. The most important thing is that these clips change color from clear (frosted) to red or blue or purple or yellow or orange, etc when exposed to sunlight (UV - ultraviolet light). Are you familiar with color change (photochromic) products? Have you made these in the past?Can you also produce hair clips that Glow-in-the-dark? The links below are to our website... a view of the hair clips we are currently selling. We would like to produce the Dragonfly hair clip and the Butterfly hair clip and choose one of your claw designs for our new claw clip in two different sizes... all must change color with sunlight! Thank you... we await your reply... http://www.solarmagic.com/hairclip1.htm http://www.solarmagic.com/hairclip2.htm
