A deri lulav refers to a specific type of lulav that is of high quality, particularly one with a long, straight, and unblemished appearance. It is often associated with a more refined or premium lulav, as "deri" can mean something that is of better or superior quality. It is used in the traditional waving ceremony along with the etrog, hadassim, and aravot during the holiday.
These are individually inspected by Rabbi Ash, in addition to providing a premium Esrog.
