Sleekon was previously featured here on AppleTell for their glow-in-the-dark cases. Rather than glowing in the dark, the Photochromic case performs its trick in direct sunlight. All the modles feature simple black and white designs that receive a punch of color when you expose them to UV radiation. The Photochromic case is the same style as the previously-reviewed Luminous glow-in-the-dark cases.

In addition to Whale’s Dream, there are seven other case designs featuring a variety of nature and film noir/comic book styles.
