One of the ways to get CSGO skin weapons: randomly get the weapon boxes dropped in the game, and then buy the keys in the steam market. You can open the box and smoke weapons after purchase. It depends on personality. If you have a good character, you will smoke expensive weapon skins, and then you can choose to sell them at a higher price. That's why you can make money by playing CSGO.
The second way to get CSGO skin weapons: buy the weapon box in the steam market and then buy the key, and you can open the box directly. The leather weapon you smoke depends entirely on luck, but you'd better not, because you will lose money in most cases. Just to be on the safe side, please look at the next one.
The third way to get CSGO skin weapons: buy skin weapons directly in the steam market, so that they won't be opened again. Note here that weapons with the same skin may have different quality and prices, so please buy them at your own discretion.
The fourth way to get CSGO skin weapon: accept a gift from steam's big friend. CSGO skin weapons can be given to others, so make some friends!
