Perfect for searching for treasure in the sand or dirt and fits perfectly in a Scrunch Bucket! This sand sifter is made from flexible, food-grade silicones. This makes them very soft and flexible, but incredibly strong and durable. You can leave Scrunch stuff out in the freezing cold, no problem, because silicone is insensitive to extreme temperatures. What’s more, silicone is environmentally friendly, non-toxic, recyclable, and easy to clean.
