I've been told the adhesive ones aren't a thing anymore, which I vaguely remember confirming once on workbench (or at least that Target wanted us to use the magnetic ones, not that they're not orderable) when I was disgruntled the ETLs wouldn't order more. I found some packages of them in the fixture room a year or two ago and I keep them stashed away for when I set, because fuuuck magnetic dividers. I also vaguely recall the magnetic ones being on backorder at some point but no clue how long ago that was.
