Topaz is a silicate material of aluminium and fluorine on of the hardest naturally occurring minerals and the hardest of any silicate minerals.  Due to its hardness, transparency and variety of colours it has long been popular for jewellery.  It does have a low index of refraction which means if it is cut with large facets unlike other gems it will not sparkle.

In 1898, the Philippine Navy was founded and then decimated by American forces in 1899.  When WWII started the Philippines had no navy and was very exposed by the withdrawal of the US Asiatic fleet after Pearl Harbour.  The Philippines had to rely on offshore patrol boats  (OSP) of which they had five to ward off Japanese attacks from the sea. 

TWSBI was formed in 2009 as a subsidiary of the Taiwanese manufacturer Ta Shin Precision.  For over 50 years the company had manufactured parts for other pen manufacturers.
From the TWSBI web site:

Lucia was the mother of Dyesbel, (background to Dyesbel in my review of Mermaid Green).  She is the women who spent too much time looking at pictures of mermaids whilst pregnant and gacve birth to one.

Armada is a fleet of ships, this is mentioned on the Vinta web site as is the Battle of Leyte in 1944.  This was the amphibious invasion of Leyte that started the liberation of the Philippines in the second world war.

Mars Ravelo (1916-1988) was a famous Filipino cartoonist and graphic novelist.  He wrote many famous stories but the one that has remained popular through the years in Filipino culture is the story of Dyesebel.  A Mermaid born to human parents.   

After a break I have come back to Vinta inks as I recently got my hands on some of the pastel shades and thought I would complete reviewing all I had.   The first of the pastel inks I tried was Violet (Maskara 1890) and though I find it pale seeing it in the flesh so to speak I can understand why this ink is so popular.

PenBBS inks have been made since 2005 but it is only recently they have been making an appearance outside of China.  This is the one  PenBBS ink I own, it was part of an ink sample box.  I had been reading about Pen BBS inks (love their pens) but couldn’t find them anywhere to purchase.  A lot of trawling through the web reveals they are no longer available through aliexpress but can be bought via ebay at about UD$7.50 a bottle.  However, the adverts come with the disclaimer they may not able to be shipped to me.  The alternative is Vanness pens who now stock 43 colours at US$16 for 60ml (27c/ml), so tempting as there are some very nice colours .

3 Oysters inks are made in South Korea, they are pH neutral made from water-based dyes so are not permanent.  Apart from that there is nothing more I can tell you about the inks despite many hours searching the web, one website may have been helpful but it was all in Korean.

This ink is a collaboration between Mont Blanc and James Purdey & Sons the very very expensive British bespoke sporting guns and rifles maker.  I was not sure how guns would link to a single malt but according to Mont Blanc this scented ink is inspired by single malt whiskey and the post-hunting ritual.
