The Collection tab contains all of the player's cosmetics
Cosmetics are items that modify the appearance of weapons or the player's account in VALORANT. There are 5 types of cosmetics; gunbuddies, cards, titles, sprays, and skins.
Summary
Cosmetics can be changed and equipped in a player's Collection tab. Methods by which they can be obtained include Battle Passes, contracts, and the Store. Most types of cosmetics have some that are available for purchased using Valorant Points. Others can be unlocked using Radianite Points or solely through game progression and Experience Points.
Gunbuddies
Gunbuddies are weapon charms that attach to the side of weapons.
Player Cards
Player Cards are images that change multiple parts of a player's account, from their icon to their loading screen banner and their background image seen by an enemy when they kill them.
Player Titles
Player Titles are the titles shown beneath everyone's in-game name while in the lobby or while in the game loading screen.
Sprays
Sprays are images that can be applied on any map surface. Players can equip three sprays; one for pre-round, one for during a round, and one for post-round. Some sprays are animated and other also have sound effects.
Weapon Skins
Weapon Skins modify the appearance of weapons. These can be as simple as recolors to as complex as turning the weapon into a dragon.
There are five tiers of skins, called editions, going from the simplest to the most complex; 
Select, 
Deluxe, 
Premium, 
Exclusive, and 
Ultra. Melee skins are the only skins in the game to all be classed as Exclusive, though their prices (for melees that can be bought) are usually related to the edition of the bundle they are associated with.
Collections
Some cosmetics share the same theme, allowing them to be grouped as a collection. Some collections are just made up of assorted cosmetics that share a theme, whilst others come in bundles that allow players to obtain all the cosmetics from that collection in one go.
