Regular Caches are containers that are large enough to hold a logbook and still have plenty of room left over for trade items.They can range in size from small tupperware containers to large buckets or barrels. The perfect cache container has to be an H83 or H84 ammunition box as they are sturdy, waterproof and will last for years. Do be sure to paint them and label them correctly so that anyone finding it will know its a geocache.
