It may be a one-of-kind game or edition, an item with many small or delicate parts, or in a state of frailty due to old age. In other words - priceless.

In many cases, such items would be locked away behind glass in museums or collector's homes, but we feel that defeats the intention of the item, which after all was conceived and built to be played with. So at Conundrum House, we gladly allow players to play with these priceless items - with appropriate reverence and respect for its condition.
