Cardboard box for microwave if you can (Relubbus TR20)

I need a cardboard box approx 19'' x 11'' x 15'' (50cm x 30cm x 40cm). My elderly next door neighbour bought a new microwave but because she is partially sited it was unsuitable. I have arranged to return it for her but her husband had recycled the packaging. If anyone has a suitable box I would be very grateful .
