Roll Needle / Needle

Roll Needle

Have you ever lost a needle?This small item seems pretty dangerous.Only through searching each detail on the sofa can you have a chance to find the lost one.Actually,we consider that needles need to be sharp only when sewing.
Roll Needle utilizes the characteristic of shape memory alloy,which can change in shape with the temperature change.
When sewing,you pick up the needle,stroking it along its tip,then your hand's temperature can wake up the tip.Roll Needle rolls up again with the heat dropping to the room temperature,while put down.
Thus,you will never prick yourself on a needle when not using it,since it is curly and gentle at that time.
