I'm new to trading items from dota. I did once years ago. I believe this is my steam link inventory https://steamcommunity.com/profiles/76561197993691531/inventory#570

I have 2 arcana that I didn't even know about. One is Crystal Maiden Frost Avalanche. The other is Techies Inscribed Swine of the Sunken Galley. I was trying to just sell random cheap stuff with Steam Inventory Helper. Are these only tradeable is that it? If yes, can I trade them on here. The price next to them from the addon shows $23.50 and $18.00. So would like to trade not for money of course for FG. Cheers let me know, not trying to do anything I can't.
