TBH I have brought many from all over the world.
But over the last 5 years I have been buying from CSUSA, yes there is import taxes to pay and VAT to pay, so what, its the quality of the kits I have become to really appreciate..
I still have loads of cheapie kits that I purchased quite a few years ago but got to the stage as though I couldn't be bothered to make them, if I do then they are usually give a ways to charity for raising money or the grandson to learn pen making.. you just don't realise how many a child can get through..
