White is one of the most difficult colours to print. To print a white on a coloured background with an ink is even more difficult. WOW!has three shades of white powder which are completely opaque and this one will raise to an honest bright white regardless of the background colour.
If you are buying from outside of the UK you may now be charged additional fees/customs charges when the order arrives with you. Sadly I can not advise what these charges will be and I can not cover those fees for you.
