The Sharp EL287BBK desk calculator is made from 100% post consumer recycled plastic & also features a dual solar & battery system. Large 16mm high digits together with a fold away kick stand help make the LCD screen easy to view & to reduce any potential misreading of numbers, the EL287BBK features 3 digit punctuation. To avoid any keying-in errors, the keys are organised into different colour groups with the 3 key memory in an easy to identify green colour. The ELR287BBK LCD display is protected by a glass top clear acrylic panel to prevent dust & grime from building up along the edges of the LCD & Solar panel & this also adds to the aesthetic appeal of the calculator. For those who are conscious of their environmental footprint, the ELR287BBK is the perfect business accessory!
