The Thread Cutterz Adjustable Rings is a handy tool that you can take with you anywhere; they are even TSA allowed! These adjustable rings have a double-sided, stainless steel blade that quickly and efficiently cuts through thread, embroidery floss, and yarn. The Thread Cutterz Rings are one size fits all thanks to the adjustable velcro straps. Choose from two different styles! The Thread Cutterz Rings are available in basic pink and black. You can also add some sparkle to your cutting tool by choosing a ring that features real Swarovski Crystals. Each ring is hand-finished in the USA.
