Does a custom shape make a whiteboard less durable?
Not inherently. The core writing surface performs the same regardless of shape; durability differences come down to edge finishing and mounting quality.
Where does wear typically show first on a shaped whiteboard?
Corners and narrow points in the outline are usually the first place any wear becomes visible, more so than the flat central writing area.
Does an unusual shape need special cleaning?
Not special products, but a bit more care around tight corners and narrow points helps prevent residue building up in ways a flat edge would not show.
Should mounting be different for a non-standard shape?
Often yes. Weight distribution can differ from a simple rectangle, so mounting should be matched to the specific shape rather than treated as standard.
How can I check if a shape will hold up over time?
Ask to see an example installation that has been in daily use for at least a year, rather than judging only from a new sample.
