Diamine's Invent Christmas Inks were originally introduced in 2018 with their extremely popular 'Inkvent' advent calendar. Behind each door you would find a small bottle of fouintain pen ink with a festive theme, such as the iconic Jack Frost blue or Mistletoe green. Since then, the colours have proven to be a popular choice for fountain pen enthusiasts and Diamine have released all twenty-five colours in a beautifully designed 50ml ink bottle.
Some of the Diamine inks include special properties, such as 'Shimmer', 'Sheen' and a combination of the two in their 'Shimmer & Sheen' colours. 'Shimmer' ink contains glitter, 'Sheen' provides a slight variation in colour when writing and when combined you experience the best of both.
