From Amazon as well, but adhesive clips
50 Pack Adhesive Cable... https://www.amazon.com/dp/B085XJ8PGG?ref=ppx_pop_mob_ap_share
Edit: I've used these before and fyi, they're cheap and so sometimes they don't stay stuck. It is what it is. If you stick them where you want them and give them 30 minutes before putting the cables in, that helps. But I mean I've probably had 3 fall off of the 50 I've got up around the house. So it hasn't been that large of an issue
