9 x 1 3/4 Premium Quality Straight Wine Corks 1000 ct - have agglomerated centers and Natural end caps.  Premium Quality is our high-grade cork.  These are great for wine that will be stored up to 10 years.  The #9 diameter and the 1 3/4 length makes them very difficult to insert with a hand corker and we suggest only using them with a floor corker or better.  These corks fit all of our wine bottles excluding the 187 ml champagne bottles.
