Review on Bottle Lamp Kit with 9mm Glass Drill Bit: Transform Wine & Liquor Bottles into Stylish UNO Slip-On Socket Lamps with UL Listed Wiring Parts and 8ft Black Cord by Wade Meeks

Very easy to use. It comes with three different sizes of cork, depending on which bottle you want to use. You have options. At first I just used a cork connection at the top with a string sticking out. (no drilling) I liked it but after reading the instructions how to drill a hole in the bottom of the bottle to hide the cord. I tried. They give you a drill which is great. I followed the directions and now I have a professional looking wine bottle lamp. I love it and am happy with my purchase.
