Seulgie has released a a second colorway of her uni-horn Birthday Satyrs (first Baby Blue version sold out from myplasticheart) online, but alas as of this post, they are listed as "Sold Out"! I'd recommend you stay connected via her Instagram @seulgie._, in case you've already not, that is :)
Dropped June 21st, Seulgie explained;
"This colorway is what I had as the second option for one year anniversary release. I got five darker pink hair pieces by mistake… Wish good luck to those who missed baby blue Satyrs!"
