Missing Cajon – please help

Good morning,
Did you know that a Cajon is a musical instrument? It looks like the a box – much like a stool, but in fact it is a percussion instrument, also called a drum box. We have 2 cajons in school now: one in Bonnie’s music class, and one that belongs to Rick in one of the LSS classrooms. One of our student’s cajon has gone missing. It is pictured below. It is black, was last seen in a black cajon bag, and measures 28x48x28cm. If you have seen it at school, please let me know.

Thank you,
Arden
