A funky and stylish pair of multi-purpose steel candle holders... This Galerie set is by Menu, Denmark, and was designed by Pernille Vea. They are circa late 1990s or early 2000s and now discontinued. Simple modernist, industrial and Scandinavian in style, and perfect for any interior. 
They're two part versatile holders that split apart so the lower part can hold table salts or other candles. They can also hold a cylinder glass/vase in the middle up to 5.5cm wide so flowers or feathers can be suspended within. The upper holds a tealight candle. The metal is solid silver-coloured steel. They come with the two tealight candles pictured which are probably original.
Each two-part stacked holder is 3.2cm tall x 6.7cm and a heavy 420 grams. They're in very good used condition, good for display and use with not many signs of use. A good silver coloured steel finish. Last photo is from a box found online.
