This is how you would open a bottle of N from A, the only difference is that there's no parallel lines, just the blue plastic surrounded by aluminum and rubber underneath. Also, you may want to use tweezers to avoid cutting yourself. Since the blue plastic and the aluminum are connected, to open a bottle of N from A, all you have to do is use tweezers to open the blue plastic, then pull it to the left and pull the rubber bit out (like in the video above). Some bottles of N have a central middle part and are opened with manicure scissors, but the N you would buy from A has no central middle part, just a blue plastic surrounded by and connected to aluminum with the rubber bit underneath.
