Non-shop Dye
From The Wajas Wiki
Non-shop dyes are limited release dyes that cannot be purchased in the regular Dye Shop. Non-shop dyes are available in user shops, auctions, trades, and occasionally the Leaf Exchange and CWP Shop. They are also often referred to as "OOS" dyes, which stands for "out of shop", referring to the fact that they cannot be found in the Dye Shop.
The following OOS dyes are also available as markings during custom creation.
