Under the small loops of the Maths model hides a press stud to open your bag more quickly. In order not to lose them, we advise you to always leave the loops threaded in the straps of the flap.
You can order new loops for your bag here; they are delivered in pairs. Choose the color closest to your bag. Don't worry if there is not the exact color, once the loop is passed through the lanyard, its color cannot be seen
