Purchased #8 Sakura: Made a perfect sakura mold that stayed together when removed. The silicon is extremely flexible, so be careful not to spill the liquid while transferring to the freezer. The silicon also has a slight scent to it, even after being washed, I don't think this affects the food though. The "seal" that lays over the mold to keep the liquid in place does not fit tightly enough to keep liquid from leaking out. Each mold holds about 1/4 cup of liquid when filled to the max. I recommend not filling the molds all the way full. Experiment with the amount that works best for you to avoid spillage when moving to the freezer.
