The Weighted Pour Spout fits in multiple sized olive oil, wine, or liquor bottles. The convenience is only having to use one hand to pour, with a fine stream of oil or vinegar to put on plate or pan, or directly on your food.
The Tapi Pour Spout is made of rubber and can be washed in the dishwasher. The top comes off and the bottom stays in the bottle. The nice feature of this spout is the dip lip and controlled pour. Secured from air when sealed as well.
