The workmanship is good and the presentation quality, although it actually only multilayer cardboard with punched Lächern is. The alternatives in canned form or as a pocket have I not promised, either because they are not expandable, or priced out of the ordinary.
For 10 euros (or 20 for both Infinity Sets) you get here a balanced collection system and to park the flying coins neatly in book shelf.
Highly recommended.
