These items are Gachas, they are allowed to be sold. They have Gacha fairs in SL where you buy your gachas and can resell them. The creators make them with common pieces and rares, making some pieces worth more than others....its like any other type of collecting, you gain things of value and you can hold onto them to get more value or sell them when you see fit...Do not accuse me of something like that again thank you.
