LOVYCO Yellow Needle Easy Stringing Apparatus

​ "Hello, the use of the product is very simple: ​ Insert the needle into the ear device's groove with the hole facing down. ​ Press lightly on the button/flapper (thus a small hook will pass through the ear of the needle). ​ Hang the string on this hook. ​ When you release the button, the thread will automatically pass through the eye of the needle. ​ You can take out the needle easily. We wish you a good day!
