What Happened to Mag-10?

What happened to Mag-10?? I can’t find it in the store and links in e-mails to it don’t work.
I wanted to buy some … I missed the announcement that it was discontinued. It was out of stock for a long time and then disappeared.
Is there a replacement or something like it that I can still get?
Thanks,
Chris

Unfortunately, due to massive supply issues, Mag-10 has been put on hold.
