This is a nice "super stubby" stainless steel guitar slide, perfect for standard guitar or cigar box guitar. The slide is 1.10" (28mm) in length, with an inside diameter of .827" (21mm) and an outside diameter of .984" (25mm). The wall thickness is 0.157" (4mm). This shorter style of slide is good for playing partial slide, where the slide is used on some of the strings while the other strings are fretted with the fingers or left open. We include a piece of self-adhesive faux moleskin with each slide to help you size it to your finger. Also be sure to see our other slides in different sizes and materials!
