The Tovolo Flex-Core Jar Scraper reaches the last spoonful in peanut butter jars, jam jars, sauce bottles and blender containers. Choose a stainless steel handle or a natural wood handle. The narrow silicone head slips through small jar openings and reaches the bottom, and the angled tip works into corners. A curved shoulder swipes along the underside of the jar lip where residue collects. The curved front scoops while the flat back spreads condiments, nut butters and frosting. A Flex-Core nylon core keeps the head firm in thick spreads and dough, while the flexible edges press against container walls. The BPA-free silicone head is heat safe to 600 degrees Fahrenheit. The stainless steel version is fully dishwasher safe. On the wood version, the silicone head is dishwasher safe and the wood handle is hand washed.
