Cable seal is a disposable lead seal product, which is usually used to seal boxes or bags. 

Here are the steps to use the cable seal:Check whether the keyhole of the cable seal is blocked, whether there is rust inside the lock core and whether the plastic head is seriously deformed. 

If there is, this cable seal cannot be used.

Choose a suitable place and insert the cable seal on the items that need to be closed. Pay attention when you insert it, when go through the keyhole,fingers can feel the obvious locking force of steel balls and make a crisp sound. 

If the steel wire passes through without obvious steel ball buckling strength and crisp sound, it means that there is rust or steel ball displacement inside the cable seal, which will be a useless cable seal.Pay attention to the length of the cable seal after the insertion is completed. This length should not be too long or too short. If it is too long, it will be more troublesome to destroy the cable seal in the later stage. If it is too short, it will be impossible to guarantee whether the cable seal can effectively lock the steel wire.

Use wire cutters to cut the cable seal.
