This is slightly smaller than the Original Regaliz®, but not quite as small as the Mini Regaliz®.  It measures 10mm x 4.5mm.  It is thinner than original Regaliz® and has a squared off oval shape.  We offer four styles of this 4.5mm leather, including plain, metallic, stitched, and two-toned.  The plain and metallic leather look great alone, or jazz them up with a few of our classic spacers.  The stitched style is very popular for men's bracelets.  The 4.5mm Regaliz® offers a simple bracelet alternative-- great to stack in a pile of other leather bracelets.  If you find that some of the 4.5mm spacers are loose on the leather, try adding 10mm rubber o-rings to secure spacer in place.
