This is a very good example of an antique treen Lignum Vitae dice shaker. Note on the inside there are a number of grooved circles going around the inside all the way down the whole length of the shaker. This is for the corner of the dice to catch and be turned.
It is made from lignum vitae and has some incised line decoration on the outside.
It measures 9.2cm h x 5cm w.It comes with an early 1800s bone dice measuring 1.2cm.
There are many items described as dice shakers which are not true ones having no grooves on the inside or having a few at the very top.
