I wanted to introduce this great place for anime merch on carousell.
I've bought from this seller before and they were very nice, we met up in real life and I received the file in perfect condition, wrapped neatly in plastic. They even helped me with directions to Heartland Mall which I was finding at that time.
Seller mostly sells anime merch but she has this customize series, where you can pick any image you want for a certain merchandise, phone cover, LED keychain, mousepad, pillow. It's not just for anime stuff but any image you want.
For those interested, pre-orders close on every Friday.
