Do you know what the SKUs are for these packs? Possibly GBR16 and GBR19?

Sorry for the delay, these are GBB81 and GBB82, there is DTV15 above the barcode.

Are those the SKU’s for the pictures of the 7 packs you posted?
Did you buy on Amazon,in a store,or???Thanks. I think those are listed on Walmart.com (US) right now but with different SKU’s.
Any help would be appreciated for my family’s collection(obsession). Thanks!

I got these from Amazon, order that I placed 3 months ago that was finally shipped.
Thanks for the WM links, those will be very helpful. I wonder what GBR16 and 19 will be.  Based no past releases, there are usually 4  of these 7 packs each year. Most these will include one or two from the blind bags, so we end up having duplicates. I am not unpacking these until Drew adds them to ixbyix.    Since these look like brand new releases, possibly part of 2019, I think Drew will wait for more releases and will add Unnumbered - 3
