This artist has certainly never dealt with actual long hair before if he thinks you can use a rubber band as a hair tie. Protip, never do that, it will rip half your hair out.
Well “wa gomu” is the same word for both.
But they use some straight up black rubber bands (smoother?) here 🎌, I’ve seen them for sale.
Also for the mom who’s sick of it they sell just spools of elastic cord, you just cut off a piece and tie a knot
