Hello. I bought the Abus BORDO Twint Set 6000 product two days ago. The item makes a very solid impression. But now I think that not everything has been delivered. Based on the 2nd of 4 photos, I firmly assumed that the optional fastening option (two straps each) for flexible fastening was also supplied with the item. At least that is what the photo suggests. Have these been forgotten and will they be delivered later?
