Box of 4 mini silver Christofle salt shakers

Box containing 4 mini glass salt shakers and solid silver cap from christofle. The lid of the original box has been consolidated inside but remains perfectly functional to store the 4 salt shakers. The caps are made of solid silver (oxidation on the inside side - see photos). The glass containers are in good condition (no chips or cracks) but 2 of the 4 remain a little bleached inside despite cleaning (the other 2 are perfectly clear and have probably never been used). Box dimensions: 14.5 X 4.5 X 4.5 cm. Dimensions of a salt shaker: height 4 X diam 3cm approx.
