The piece measures 11-1/2" X almost 8" x 1-1/2 to 2" deep (the sides are scalloped).  Medium- brown wood tone, probably finished with linseed oil per Google.

Made by Finnish craftsman Bo-Åke Ljungars, and was likely purchased 20 or more years ago.

Appears to be very carefully made, the workmanship is smooth and tidy.

From a non-smoking home.
