This frameless hourglass has a super simple design allowing it fit into any workspace. The 30 minute settling time works perfectly with the Pomodoro method of studying, making you more efficient without the use of any technology. Also great for time-boxing breaks or other tasks.
Note: While the frameless hourglass design looks great, its not recommended for children and young teenagers. The lack of a supporting frame make this suitable for gentle use only.
