Features: 1.Made of soft silicone and good-quality plastic, durable and reusable. Organize threads and keep them tidy. 2.After using the spool hugger, just stretch the spool saver and hug the spool within a second. The spool does not need to be completely covered. 3.The bobbin holder can be used for most sewing and embroidery spools (except for large commercial or extra-large spools), which saves time to find small gaps on the bobbin to catch the thread. 4.These bobbin clamps are ideal for clamping on or off the spool. Convenient and practical. 5.When the bottom thread is not used, the bottom thread organizer is very helpful to prevent the bottom thread from separating. Prevent the bobbin thread from unraveling and knotting, and ensure that the bobbin is neatly stored and organized. specification:Item Type: Bobbin Thread Buddies Function: Suitable for sewing machine, spool storage device : 60Pcs(20pcs each for silicone thread spool huggers, silicone bobbin thread clamps, plastic bobbin buddies), random color Material: Silicone + plastic PackageList:60 x Bobbin Thread Buddies(20 x silicone thread spool huggers + 20 x silicone bobbin thread clamps + 20 x plastic bobbin buddies) NotePlease note that the colors are random.
