【High Quality】Made of soft silicone, durable and reusable, used to organize threads and keep them tidy. It has high flexibility and can be twisted at will, making it suitable for household sewing and embroidery spools of various sizes. 【Easy to Use】Easy to use, just stretch the spool saver and hug the spool within a second, the spool does not need to be completely covered. Helpful to prevent the thread from separating, can prevent the bobbin thread from unraveling and knotting. 【Space Saver】These thread spool huggers are thin enough to create no space issue when being stored in your thread rack or case. Saves time to find small gaps on the bobbin to catch the thread, ideal for clamping on or removing from the spool. 【Widely Used】Can be used for most sewing and embroidery spools (except large commercial or oversized spools). 【Reuseable】With the flexible silicon material, these thread spool huggers will always curl back to original shape after taking from spools. You can adjust them to fit other spools even after repeated using.Package List: 100 x Bobbin Holder
