My earliest glass was a practical scout glass made of sturdy brass. I studied insects and the skin of my hand. However, after I turned my father's newspaper into charcoal, it was confiscated, even though I asserted that glass was an essential tool for scientific discovery. Our discovery glass allows a detailed examination of cards, coins and other wonders. Colour: bronze Material: brass & glass Dimensions: LxWxH: 13 x 5.5 x 1.9 cm
