2 vintage metal and glass shell butter dishes with knife

Set of 2 vintage silver-plated metal (tinplate?) shell butter dishes (scallop shape). Composed of a translucent blue glass receptacle and a knife. It can be used not only for butter but also for putting jewelry in it. Perfect for serving salted and sweet butter (the Bretons will tell me that one is enough for salted butter 😉). It is possible to buy just one on request. Good general condition, one with some internal marks that I have not managed to remove, but this is not visible if you leave the glass part inside. Another whose glass part must have had an internal shock but this does not affect anything. 📐 set: width 12.5 cm X depth 14 cm X height 12 cm Glass part: width 10 cm X depth 9 cm Weight of a butter dish: approximately 220 gr.
