Ditch plastic this summer, and cool off with popsicles made in these Onyx stainless steel molds; BPA-free & phthalate-free. We made a batch of kale and strawberry smoothies today and froze them in these beauties. They are not cheap, but they are a summer investment and they should last forever. The only thing you need to continue to buy are the wooden popsicle sticks. These appear to be a better alternative to silicone, which is still a synthetic polymer. Give this kale smoothie recipe a try!

*Update: We found a CHEAPER version with a far better design.
