In this case, the elastic band provides multi use:
1. Does the course side of the block together and
2. Does my Faber Fineliners wonderfully solid. So that getting a pin is palpable.
This block is certainly something -auch- for aficionados of the extraordinary. In relation to its extras he is worth the price in my opinion. Anyone looking for a simple block is safe elsewhere here on Amazon for less find. But who wants the Budget, when he may have something special ...
So, good workmanship, many useful extras = 5 stars.
