[Snap-fit assembly – no glue, no tools required]: Some spools require tape or glue to secure the ends. This product uses plastic buttons. Simply push the disc onto the spindle and press the button to lock it in place. It can be just as easily dismantled when no longer needed. [Write directly on the paper surface – no need to peel and stick labels]: Plastic and wooden spools require labels if they need to be marked. The paper surface can be written on directly with a pen or pencil. Mark the type, colour or length of the cord on the flange of the spool. When winding different types of cord, simply write over the existing markings. [Flat discs stack like plates – columns stored separately]: Assembled spools take up valuable drawer space. The components of this product are flat. Stack all discs like dinner plates. Bundle the cylindrical parts together. Assemble only the required quantity. Keep the remaining parts neatly stored. [Quiet on hard floors – no plastic clattering]: Dropping plastic spools onto tiled or wooden floors produces a sharp noise. These paper spools make a dull thud when dropped. If you are working in a shared space or late at night, you will not disturb others. [Store in a dry place only – not suitable for damp basements]: Paper absorbs moisture. Storing these spools in damp conditions will cause them to soften and warp. Please keep them in a plastic box or a dry cupboard. Do not leave them in an unheated garage during winter.
