How do you get more crafting inventory slots?

Thanks! That's what I was afraid of. Simply typing "inventory" only yields "25 Furnishing Inventory Slots Kit" and nothing else. So there must not be Crafting Inventory Kits available. As a matter of interest, how are they gotten in the first place? Is it by some quest? Inventory slots bought for Plat can't be traded I think and I do not believe the Minstrel vendor sells Crafting Inventory Slots.

Crafting slots can be bought with plat from the store or gold from auction .
There's still no other way to get them as far as I know .
