Silicon ice molders

I was looking for an ice molder that is big enough because I noticed that bigger cubes doesn't melt easily but if you want to have an easier way to make your drinks cold, stir a lot of small ones instead. I thought that this would be the one that I'm looking for but it was not. However, what amazed me about purchasing a silicon ice molder is that taking off the ice cubes is a breeze comparing to a non-silicon. You wet the outside bottom part of the molder and then pop it out using your thumb.
