Plug made of wood with convex opalite

This plug consists of two organic materials: wood and glass. Glass is an organic material made of liquid sand. 

This plug is a delight for the eyes, as it includes the warm color of the wood and the milky color of the opal stone. The opal stone, as you can see in the picture above, features two different shades. The main color is white, but it also shows blue, pink, and orange shades, depending on the light that hits it. 

The size of the opal stone is proportional to the plug's diameter. The opalite is convex on the front side, and flat on the back. Since the wearable area of the plug is made of wood, it's not recommended to use in damp areas, as humidity can cause breakage. Similarly, water dissolves all kinds of glue over time; since the opal stone is glued to the plug, there's a risk of falling off. Therefore, we strongly discourage using this plug in the bathroom, for example.
