Elm + Otter Montessori wooden toy sorting set with wooden cups, balls, acorns

Wooden Montessori inspired toy set from Elm + Otter. Comprises 7 wooden bowls painted in muted tones, each with a matching wooden ball that fits inside (photo shows 6 balls but there are in fact 7! Oops), and 3 corresponding wooden acorns for sorting (note: blue bowl only has 2 acorns). EUC no flaws to note.
