Transparent swirls rarely get pinned down by maker.
I wondered if someone might find the texture and bright whiteness of the ribbon distinct enough that they might claim it as CAC, but when I compare it to the transparent swirls in this thread for instance, it's not seeming as if it would necessarily fit in. https://marbleconnection.com/topic/7815-cac-trans-swirls
Most of those swirls have a bubbly base, but the blue base ones look clear. Maybe someone will think the yellow base belongs also.
