Halo Rings are like having an extra set of hands! The self-adhesive backing sticks to your machine, your cabinet, your drawers (anywhere you want to stick them!) and holds your pens, pencils, chalk liners and more. The secret to the Halo Rings versatility is in the expanding ring - it can accommodate items from 0.25in to over 1in thick - no more rolling off of the cabinet! But that's not all - they work great for scissors, tweezers, seam rippers - anything you want to keep close at hand AND keep track of. Trust us - you will wonder how you lasted so long without Halo Rings.
