Sleek design meets cutting edge bioplastics! The all new iPhone 4 cover is as usual made of plants, letting you protect your iPhone 4 in style and with a clean environmental conscience. We developed an advanced bioplastic material mix - exclusive to bioserie - that considerably improve the strength and durability of your iPhone 4 cover. Our popular and now patent pending feet are placed at the corners of the cover, giving your iPhone 4 screen protection during face down placements on flat surfaces. Specially carved out flash window prevents hues and unwanted coloring during flash photography.
