This is a Tupperware set of a sheer white bowl and two different bright yellow lids. One is the colander/strainer lid, marked Tupperware, but I can't find a number on it. The other is a grater/slicer lid number 1849-4, with inserts that switch to be either a grater or slicer. The grater insert is number 1852-3 and the slicer is 1853-1. There is also a small white curved dish number 1851-3. The bowl is 10" wide and 3 1/2" deep. All the pieces are in excellent condition.
