This is Shane Speal's #1 slide.  Short for fast playing, but heavy mass for all the sustain you'll ever need.  Made from industrial steel, it ain't pretty, but it's all about the TONE!
 
At just 1.5" long, a diameter of .75" (Men's ring size 9.25) and a sustain-inducing mass of 2.2 ounces, they're absolutely perfect for cigar box guitar playing.
 
Composition:  Industrial steel
Finger Opening:  0.75" (19mm)
Length:  1.5"  (38mm)
 
Each slide comes with a strip of self-adhesive felt so you can line the inside and size the slide perfectly to the top of your finger.  Shipped in its own burlap mojo sack.
