It seems the hottest new green products being introduced these days are made from recycled plastic bottles. Samsung and Motorola have both introduced phones made from recycled PET plastic, and now there’s even a boat being made from it. So it’s no surprise to hear stylish laptop case producer Kena Kai is going to be making a special notebook sleeve made from recycled plastic too. The new line, called FELTtech sleeves, will be available for purchase online and in stores this Earth Day (April 22nd). Although the dimensions of their other cases are limited to hold MacBooks or a similar sized notebook, this special collection will come in 3 sizes: Netbook size, 13.3″ (MacBook size), and 15.4″ (standard size). The sleeves will be retailing for between $30 and $40, and will make a perfect present for Earth Day. For more information, visit KenaKai.com.
