Need back panel for Ikea corner corpus 73x73 in black-brown

Hello Ikea community

while assembling our new corner cupboard, I damaged the back panel. Does anyone have an idea where I can get/buy a back panel in black-brown?

Many thanks in advance for the numerous tips :)

Best regards, Mustafa

Hello,

possibly in the Ikea Fundgrube. Otherwise, have a corresponding hardboard cut to size at the hardware store; they are available with various decors.
