Elgrand E52 Luggage Board Trunk Board Since this is handmade, please refrain from purchasing if you are looking for perfection. The 18mm thick lumber core board is covered with carpet. It is sturdy and does not bend even when you apply some weight by hand. The luggage space becomes flat, making it easier to load luggage. For those who want to use the trunk space more widely, or those who are having trouble with luggage rolling around, how about it?
