...we've heard this often. Indeed, the TASCHENBEGLEITERS SO_20, SO_22, SO_23 didn't have one before. As you wished for it so frequently, we've made the change. The knotted round elastic runs through a metal eyelet on the back of your TASCHENBEGLEITER. If you don't want an elastic closure, simply pulss it out. Thanks to our community for positive and constructive feedback. In the shop you will also find a tricolored set of elastic closure. See all here.
