The Craftpro kits blanks are widely available, imported and distributed, as has been said above. I may have got it wrong but I thought most knew of them prior to posting this thread.
However, the reason for the post was to show the different sizes as some of you may not have noticed and then find its a different size when you get it.
The smaller blanks are OK but limits you to what you can turn being 4mm thinner.
I don't really see much benefit it being 150mm, there are only a few kits that need the longer blanks that the TB one wouldn't cater for.
They are ideal for two piece kits and gives you a little bit of spare for key rings or the like to match.
Thought it was worth sharing tho.
