9cm Sand Timer
The Sand Timer is an elegant, impressive accessory for your desk.
This is encased in a nice natural finish wood frame.
An hourglass has two connected vertical glass bulbs allowing a regulated trickle of material from the top to the bottom.
Once the top bulb is empty, it can be inverted to begin timing again.
Sand clocks are also useful for timing speakers and playing games.
A nice executive gift for the office.
