1 Flat Transparent Clear Marble 18 mm

A domed face that enlarges, a flat face that rests

This eighteen-millimetre pebble has two distinct faces: one is flat and serves as a base, the other is domed. As the material is translucent and colourless, the domed face acts as a small convex optic and enlarges whatever lies directly beneath it.

What you can read through it, placed on a text

Placed on a printed page, this pebble can enlarge the letters it covers while resting steadily on its flat face. The effect is clearest when the flat face lies directly on the printed surface.
