Strange package in the mail 3 months after graduation

I graduated in December and this morning I woke up to an unexpected package. 2 each of ~3 or 4 ft long red and gold cord/tassle things. I dont know what these would have been for but I assume they're some kind of decoration for graduation. Have to say, graduation was a shitshow in terms of them not acknowledging my honors or sending me what I was meant to get, so its not that surprising that they would send me some random thing 3 months late. Anyone have any idea what these things are (other than garbage now)?
