Theres something homey about having oil and vinegar dispensers on the kitchen or dining room table at all times. And then theres something messy about actually using them at the table. Most dispensers dont cut off the flow of the oil completely after pouring, causing the oil to spill when the dispenser is returned upright - and any table, especially a wooden one, takes a beating. The BISTRO Oil and Vinegar Dispensers come with a pointy plastic beak which cuts the flow of oil and vinegar very precisely hence, no messy tables. A little silicone ball in the lid closes the dispenser when its standing upright, and then moves up to open the lid when the bottle is tilted, allowing for easy pouring. The dispensers are made from plastic, silicone and borosilicate glass.
