The Mono Graph Shaker Mechanical Pencil from Tombow utilises the "shake mechanism," which advances the lead by shaking the pencil back and forth.
The "shake lock" can be activated by pushing the clip upwards, to stop the lead from coming out while it is shaking from being in your bag when you are traveling.
All with the Tombow guarantee of high-precision writing and erasability.
In the first photo, the colours from left to right are: Cherry Blossoms Pink, Ice Blue, Cream Yellow, Coral, Mint Green, Lavender.
Other colours also available.
A little reminder to drink some water! 💧
