B>6 Bellflower Concentrates + Arwen's Glass shoe

Buying 6 Bellflower concentrates. I just need 6 more for a quest and apparently they can only be obtained in PPQ which I can not do. I'm thinking around 5k each or we can negotiate a price

I'm also buying Arwen's glass shoe. Leave a price here or we can negotiate one if I'm online.

I am pretty sure bellflower concentrates are dropped by bellflowers.

Well according to strategywiki;

Bellflower Concentrate can be gained from special Bellflower Roots located at an optional stage inside the Herb Town Party Quest.
Ginseng Concentrate is dropped by all monsters in the main stages of the Herb Town Party Quest, and can be found from the treasure chests located inside as well.

I rather not end up hunting regular bellflowers if they don't even drop the concentrates. :/
