The RSVP Collapsible Silicone Funnel expands to sit sturdily on top of most bottles, jars, and then collapses to fit neatly in a drawer. Permanent, accordion style pleats ensure compact storage. When fully expanded the funnel is 4-Inch in diameter and 4-Inch tall with a 7/8-Inch spout. Made entirely of silicone, it is heat and cold resistant and dishwasher safe. RSVP International creates high-quality kitchen gadgets, cooking utensils and baking tools with unique designs to match anyone's taste.
