We now have most sizes of Addi CrasyTrio (FlexiFlips) back in stock. We are still waiting for size 2.5mm.
UPDATE: The latest information we have is that there has been some significant delays in the production of size 2.5mm needles and they are now not expected back in store before March 2019.
Limited supplies - if you are keen to have these needles I recommend to be quick. They tend to sell out incredibly quickly.
