I ordered this item for my laptop size 17.3 ". The clips are metal with button to open and close the strap which prevents your strap coming loose in the open carriage (which had already happened other bag and my computer was solved by earth that had screwed my previous computer in the farm), these attachments at the straps are therefore very important. In addition, the quality of the case itself is quite remarkable with reinforcements throughout the frame (each edge is reinforced). The general appearance and finish are perfect, very elegant. It is definitely the best bag! And all for a price / quality ratio unmatched by other brands or models I saw! I can highly recommend you :-)
