Its thickness feels somewhere between Sleeve King penny sleeves (soft, flimsy and easily scratched), and a premium sleeve of any brand (notable thick, stiffer, holds a flat shape).
These are a high-gloss surface, but are pliable enough to look like a higher quality penny sleeve than Sleeve Kings penny sleeves (possibly also Mayday- I've no experience with them). These would be excellent for archiving and you require high clarity, but if you don't like the idea of playing with cards still in packaging bags, get some other premium sleeve instead (such as Gamegenic Prime or Dragon Shield).
A diverse set of factions to play all with their own strengths and weaknesses This is one of my favourite board games of all time and fully recommend this to anyone to play and this is a great start to get into it with differing factions included to fight against each other. Along with the needed dice and board to play.
Arrived fast and in perfect condition, and also an awesome faction to play!
The Box is, in fact, White.
