Buying Flutes for 51 gil and then desynthing them gives 1 parchment per NQ, a stack of parchment sells for almost 10 in Alexander server. Lightning crystals are like 2k a stack MAX. And can be farmed. All in all, with about 3k gil max you can sell these and make about 7k profit, but they ring is a key factor to that because if you HQ you only get maple lumber
Actually a really good use for this item is if you synth warp cudgels wich you have to also make oak cudgels to make. This keeps you from making oak cudgel+1 and having to risk a desynth to get your lumber back.
