This tippet spool holder holds up to 7 spools of tippet material. Which is nice if your the type of person that chases multiple species of fish with only one or two rods. It attaches with a carbine clip to a D ring on your vest or backpack or just clip it onto your pants belt loop. At the other end is a second clip to attach the tool of your choice (scissors, nipper, floatant, forceps, etc).
While out testing it today I must say I am happy with it's performance. I got my leader snagged in the trees a few times (I am still learning). Having this little gadget made finding the tippet spools and mending my leader a snap. I also liked not having to dig through my bag or pockets to find my forceps. All in all I would recommend it to anyone looking for a convenient way to carry multiple spools of tippet material, rather stand alone or as an attachment to an existing tackle bag.
