TWSBI Diamond 50P Inkwell

**The TWSBI Diamond 50P inkwell is discontinued and is no longer available for sale as of June 2014** TWSBI originally released the Diamond 50 inkwell to accompany the TWSI 540/580/Mini, and you can see my full review of it here:    • TWSBI Diamond 50 Inkwell  . Since then, they have developed a similar inkwell, the Diamond 50P, which is a more economical version of the same inkwell. Here's what I cover in this video: Unboxing the TWSBI Diamond 50P (0:45) Showing the 5 bottle colors (1:40) Comparing the plastic 50P cap to the aluminum 50 cap (2:10 and 6:35) Using the Diamond 50P inkwell to fill a TWSBI Mini (or 530/540/580) (2:40) Using the Diamond 50P to fill a standard international converter (4:25) Swapping caps with the Vac-20 bottle (4:43)
