The following is a quote from a Diamine email following a request for information from me on why two of my pens clogged during the first use of Shimmertastic inks.
'Shimmer ink particles can collect in the feed of the fountain pen but can be cleared by flushing with water'.
Therefore the pen clogged and would not allow the flow of ink soon after the first fill of the pen.
The ink was thrown away, the problem of the pen becoming blocked outweighed any benefits of using the ink.
No other ink had blocked these two pens, a 51 and a 146.
Other peoples experiences may vary and well done to all those who have not had an issue, although others have also reported clogging problems and it is a known issue to Diamine.
To give the company all due credit, because they were aware that the ink could not be used as intended, they gave me the option of a refund of the purchase price of the ink or to replace the Shimmertastic ink with their more conventional ink.
