A perfect French farmhouse kitchen combination. Beautiful  together  as a  perfectly timeworn vignette ready prop, but both are useable.  
The little seive is a very convenient size and the bowl holds a few eggs or bits and bobs, always useful to have to hand in the kitchen. 
The bowl wears its considerable age with beauty, with just the right amount of tea staining, chippiness and crazing and measures 4.5" 12cm wide and 3.5" 8cm tall. 
The seive is 19cm 7.5" long and 9cm 3.5" wide with a useful little hook to hold it in place over a small bowl for straining small quantities easily.
