It's been on my WL for ages. I neeeeeeed it! So much I will resort to evil tactics. XD
Compared to the macaron curls / tea kettles? Nope, the horns being priced at 2k csc is actually pretty reasonable compared to those ^_^; I wouldn't recommend selling it for a low price since it's pretty rare c:
[edit] I bet there will be those who will rave if you sell low because I've seen people pay 3k for it before xD
