The Original Wine Disc - Drop Stopping Pour Spout (10) no more red wine stains on grandma's white table cloth Easy to use: just roll it up and drop it in the neck of the bottle, rinse and re-use again and again Portable... just drop a handful in your pocket for easy transport... lies flat, not bulky or heavy Food grade and lab tested... if it doesn't say WineDisc on the packaging, then it isn't. You can certainly find knock-off pouring discs for a few pennies less, but often times they are flimsy and will not provide a proper seal in the neck of the bottle, resulting in leakage... entirely defeating the purpose of using a pouring disc in the first place.
