The rarity of a skin determines its chance of dropping out of a case and its price. The rarer a skin is, the harder it is to get it by opening cases and the higher its price on the market. Rarity also affects the possibility of upgrading through a trade up contract — rarer skins give you a chance to get even more valuable items. The higher the rarity, the more valuable and desirable the skin is among players!

Choosing a skin is a matter of taste, but there are a few factors that will help you find the perfect one: 1. Appearance — choose a skin that you like in style, colors and design. 2. Quality (Float Value) — if clarity and minimal wear are important, choose skins with a low float (closer to 0.00). They look cleaner and brighter but may cost more. 3. Rarity and Cost — Rare and expensive skins, such as Classified or Covert, can be a worthwhile investment. However, if your budget is limited, you can find nice and inexpensive options among Industrial and Mil-Spec skins. 4. Stickers and charms — some skins look better with certain stickers, and charms give them a special touch! Think about whether you want to customize your skin yourself, buy a pre-made version with stickers and charm, or leave it in its original form. The best skin is the one that you like personally and that brings pleasure to your game!

All CS:GO skins have been fully ported to CS2, but thanks to the updated Source 2 engine they look more detailed, brighter and realistic. Improved lighting, reflections and textures have made them even more spectacular, but the models themselves remain unchanged. All the skins you had in CS:GO are available in CS2.
