This kit includes 4 corner sections.
Each side of the corners includes small holes suitable for 3mm diameter magnets. The kit is made from 1.8mm MDF so either 2mm or 1.5mm magnets will work fine, however if you use 2mm a small gap between the wall sections will be noticeable.
This product is sold as a flat-pack kit. It is sold unpainted and requires assembly
