I also run the anime club for the district I work for at the high school. We try to go on field trips or have some awesome nerdy guests, but it does cost money to do so. Our students have made these anime-themed buttons.
All buttons are about two-three inches tall, so they are LARGER buttons. The Pokeball ones run a little smaller, but are still large.
All proceeds go to help our club! Thank you for your support!
