My favorite June Monthly Collectible item?
It would have to be Go-Gaia's first Monthly Collectible item: Horns of the Demon. [♥]
And why you may ask?
Well, I joined Gaia in 05, so I was sadly not around when that MC first appeared.
But, as I worked extremely hard and saved up enough money, and from some lovely donators, someone was graciously selling the MC on the Marketplace for a cheaper price than what was listed.
With a smile on my face, I bought the Horns of the Demon. I had that item for two years before my other, more older account was hacked. Now, I regret clicking that accursed link in that message from a stranger....
