Submerged sea floor translucent blue bowl

This rectangular container comprises a single unconstructed art piece. From the side, the translucent blue waters cover the solid base made of seashells and tiny sea stones. But even when empty, when you peek inside you can see through the water to the sea floor where the touchable shells have textures and colours that may make you reluctant to fill it.
A practical size, solid and durable, this is not an object you will want to store, but instead, one that empty or used, you will want to have on display.
Fully washable in dishwasher liquid, or just rinsed under water, you will never have to worry about preserving it or keeping it for good.
Jewellery shows depth and scale but is not included.

This piece is 9.5cm wide, 12.5cm high and 5.5cm deep.
