During a meeting with Polish Radio CEO Agnieszka Kamińska, Kornhauser-Duda submitted two items of her own to the broadcaster’s annual Choinki Jedynki fundraiser, which is now in its 19th year.
In a video message posted on the Polish president's website, the first lady thanked those who have contributed to the project.
"During this Christmas season, and in this difficult time of pandemic, we should be especially alert to the needs of others," she said.
"There is nothing more valuable in life than a selfless impulse to help someone who needs a gesture of solidarity," she added.
Funds raised through the Choinki Jedynki drive will go toward two charitable foundations, including one run by well-known actress Anna Dymna and called Mimo Wszystko (In Spite of Everything).
The fundraiser includes an auction of artworks created by children about Christmas.

The Polish presidential couple earlier this month threw their support behind an annual food collection drive that aims to help the needy in the run-up to Christmas.
