Foam brush button source--HELP!

[Yolla Bolly]

Years ago I ordered brush buttons for recurve strings that were made of foam---they lasted much longer than the rubber types available locally.  When I switched to a longbow, the need was not there and I foolishly threw away the flyer        ---it was a small company selling a handful of archery products.  Now my nephews are shooting some of the recurves I had stockpiled, and I need to set up new strings.  
Does anyone know where I can find them---a google search did not help (I am not a sophisticated searcher of engines).
Thanks,
Bruce
