50,000 SEALS!

Why don't use Ixali Oaknot instead?

Sealants burn oaknots fast, and you want those sealants, if for nothing else, you sell them for a lot of gil.

I can amass 50k seals in a matter of an hour or so, crafting things for the expert supply missions. It's easy.

What do you craft for turn-in that isn't going to cost you more gil than just buying the mats that you'd get with GC seals. Usually, if I can craft it, I'd rather sell it and get 6x as many mats off the MB than if I turned it in to the GC.
