Sorry I only use the mascara . The one thing I would suggest to anyone using tubing is that it can clump a bit but I keep an old clean wand and do a quick flick to declump. Works for me but others may have a more professional method!
I think Donna may use other items in the brand and she is very well up on all beauty brands so if she doesn't follow the thread perhaps you could leave a message for her. HTH.
