Here's a unique way to display and sell DropStop® wine pourers. Add your logo to this hard plastic holder that looks like a min-disc case and holds up to 20 pourers and an instruction card. You'll enjoy a perfect pour every time with the DropStop® wine sleeve. Just roll up these food-grade and laboratory tested Mylar discs and slip them into the top of your favorite bottle. Then pour without worrying about red wine stains on your tablecloth or furniture. When you're done, just rinse them off and they can be used again and again.
