I use the Drechslen und Mehr pen finish almost exclusively for my finishing as i was given a bottle by the toolpost.

I also use the Drechsleroel on non Pen woodworking its similar to Osmo oil and gives a lovely finish i used it to finish the
oak jigsaw boards i made for my father for Christmas another product that I really like
