--->Indigo Easero Wings<---

I have them & put them in the trades, but I don't have a clue of their worth! D:
Some users are interested in buying them, but I don't want to rip them off nor do I want to be ripped off.

I know they must be more valuable than the hatcheable colored wings which sold for around 10-12mil last time I checked. I also know that there are none in user shops, and only one in user galleries.

Thank you for your help! c:
