Have 3 large thin plastic pallets, see pics for details. They were essentially only forkliftable with how narrow their slots were, so sections of the plastic were cut on the bottom to make it pallet jackable. FYI you still need a fairly low profile pallet jack to do so.
See pics for details. In good structural condition.
$60 for all 3, being sold through a business so pickup is Mon-Thur 8-4.
