If you love Swarovski crystals, then I have the mouse for you. The Deco Mouse is a Gyro mouse completely covered in Swarovski. The Deco Mouse is adorned with only 500 crystals – you know, so that it’s not too flashy. The mouse is made of stainless steel, but honestly I can’t imagine how comfortable operating this mouse could possibly be with it covered with crystals all over, and it being so extremely oval-shaped. I can only foresee the crystals coming loose from your sweaty palms. The Deco Mouse retails for $229.99, the tackiness is free.
