A really quirky find from Paris and from a Parisian store, marked "JP Paris" on the box. Clearly a piece of dining equipment that no home should be without! 
 
They are designed to be slid under an asparagus or artichoke plate (which have an indented section to collect the sauce) to tilt it to eat the delicious sauce and juices.
 
There are six risers in the box, they are in good condition with one tiny miss on one foot which is too small to effect stability and one pin head dot on another. They are 3" long and the timeworn but functional box is original and dates from the Haussemann era Paris of the late 1800-s
