Melt the candy wafers according to manufacturers directions in a microwave safe bowl. While those are melting, place a small funnel on top of an empty squeeze bottle. When the wafers have reached a smooth consistency, carefully pour the melted candy into the funnel and let the melted candy into the squeeze bottle. Do this very carefully so you don't end up wearing any of the hot candy.
Once the squeeze bottle is full, place the lid onto the bottle. **Before you put the melted wafers into this mold, you will need to support the top of the mold as I did in the picture so the chocolate is even once you add it to the mold.
Squeeze the melted chocolate candy into the hearts on the mold.
Once you have the mold filled, carefully tap the mold on the counter so that you can get all of the air bubbles out.
Place the mold then into the fridge and let it set for 30 minutes or so. I let ours stay in there for an hour as I was working on other projects at the same time.
When you are ready to assemble the box, carefully remove the chocolate heart box onto a plate. To do this, take a plate and place it on top of the mold. Then turn the plate over while holding onto the mold. Then fill repeat the process with the additional candies you made.
Assemble the candies inside the box however you would like.
