Brands and pack quantities

Our marketplace connects you with a wide range of manufacturers. You can find professional-grade options from brands like Dragon Shield and Ultra-Pro, known for their durability and shuffle feel. Other popular choices include Gamegenic and KMC, which offer specialized textures like matte or glossy finishes. Most sleeves are sold in packs of 60, which is the standard deck size for many games, but options for 10, 50, 70, or 100 sleeves are also available for those who need extras or want to sleeve multiple Union Arena starter decks. To keep your sleeved decks organized, consider using Union Arena storage boxes.

Choosing the right sleeves for your collection

Selecting the correct protection depends on how you intend to use your cards. For competitive gaming, matte-finish sleeves are often preferred because they reduce glare under tournament lights and provide a smoother shuffling experience. If your primary goal is display, high-clarity glossy sleeves or toploaders might be a better choice to highlight the card artwork and holographic effects. Many collectors also utilize a double-sleeving technique, using a tight-fitting inner sleeve inside a standard outer sleeve to provide an airtight seal against dust and moisture. This is especially useful for high-value Union Arena single cards.
