Alright ya'll, it is my personal opinion that party favors generally end up in the trash because they are usually fucking ridiculous and frivolous. However, there are some favors that actually do what they are meant to do, which is giving your guests something that they can remember your day by.
Mag-nificient. Essentially, a photographer will take pictures of you and your guests, and print out magnets right there at the venue. On the way out, guests look for themselves on the board and pick which magnets to throw up on their fridge. It's like an extra photographer, photobooth and wedding party favor in one. BOOM!
Your guests don't need another candle, coozie or stationary. Srsly.
