Rank 2 Faction (Gear turn in)

[EdwinLi]

If you mean Grand Company, and also mean turning in items for seals, AND also mean blue items, you can't. Only pink and green items can be turned in.

Pink and Green are Rare gears.

Blue are Unique Gears

Also the gear turn in is something you can do once you reach Rank 2 Faction level for each Beast Tribe.
