Funnels are practical tools used to guide liquids or powders into containers with narrow openings. They come in a variety of sizes and materials, including plastic, metal, and silicone. Funnels are perfect for transferring liquids when cooking, storing chemicals, or refilling bottles. Their simple design allows for mess-free pouring, making them a must-have tool in kitchens, workshops, and garages. Flexible silicone funnels can be collapsed for easy storage, making them a space-saving option.
