Flip the end cap open with just the pressure of your finger by pressing where the fingerprint is, then use these cool tool tubes to store your stitching stuff. They are approximately 6" x 2.25" x 1.5" with a see-through window so you can tell without opening the tube if the tool you need is there. It is big enough to fit a pair of embroidery scissors, a small highlighter pen, a package of needles or even a small needle case (see item number 19252)
