Post #527 with close-up of HE's keys
Looks to me like house key, member card, a red (velvet)heart, feather, and possibly a car alarm remote.
I tried comparing member card with all of the ones that my wife has and did not come up with any match. (Lowes Home Improvement, Lowes Food, Food Lion, Champs, BiLo, Piggly Wiggly, CVS, RiteAid, Pet Smart, Office Depot, AutoZone, Burkes Outlet) So, I cannot make a positive ID on the member card. With that info, it would be possible to trace any activity (if any). Worth a shot IMO
I just went through all of my "member cards" and found one that could be a match, it's from Phantom Fireworks (don't judge me!). It's a wider rectangle than most, white with a barcode and numbers below it.
