beads storage bar type & length is stated in the title
bead storage bar portion ~4,25"
.
NEW SHORTER SIZE.  These are handmade overseas & came from different vendors so they may vary slightly in the size range stated in the title.  This is one extremely cool European stainless steel charm spacer beads finding - we use these all the time for putting together our designs. Both ends of this beading bar come off. Take off one end to slide your beads on for storage or for creating bead sets ... then just screw that end back on.
.
We store a lot of our bead sets on these so we know when we-re out of a particular design - keeps us really organized. Makes it really easy when photographing sets as well. PRICE is for 1 of these really cool findings for that busy European charm bead designer or person that has a lot of European beads that need to be stored! One of the photos show more than one beading bar at different angles & beads to give you an example of how this gets used - beads are NOT included.

One of our photos also shows the different choices of beads storage bars available in other listings as well.  This picture is enlarged to show detail.
