Dragon Shield Matte Dual Sleeves are my favourite sleeves. Durable and thick, dual matte are excellent for double sleeving my top commander decks. Shuffle feels smooth, not quite as smooth as KMC or Ultimate Guard Katana, but good enough considering I think they're more durable (definitely thicker) than other brands. I love that the dual matte have the black background but are in fun, flashy colours.
The "Justice" silver sleeves are a grey metallic that was a good fit for my Commander equipment deck.
Overall, excellent colour and great quality. Definitely recommend Dragon Shield Dual Mattes.
