I love these. I can eat myself sick on them. I bought them in NY all the time when I lived there. Never saw them anyplace else I lived or traveled. When I went back to NY to visit I'd buy a bunch. On a trip back a few years ago, I couldn't find them. My parents hunted all over Long Island for me, and finally found them at a place that sold all kinds of candy. I have searched for them online, and found that they are not available. Try searching for "delfa roll" or "danish ribbon".
oldtimecandy.com says the delfa rolls are discontinued. So do a few other websites. I think maybe the are gone for good.
