Are Hero Arts Shadow Inks & Stewart Superior Memories Dye Ink the same ink?

[Fortuosity]

Are Memories Dye Ink Soft Pink, Soft Yellow, Soft Green, Soft Leaf, Soft Stone, and Soft Lilac identical in every way but name and label to Hero Arts Shadow Ink Soft Pink, Soft Yellow, Soft Green, Soft Leaf, Soft Stone and Soft Lilac? If so, are the other Hero Arts Shadow & Mid-Tone inks simply Memories Dye Ink as well, just with different color and brand names?

Hello! Tami from Hero Arts here. Hero Arts designs all of its own ink formulations, and most are manufactured for Hero Arts by Superior who owns the Memories Brand. In the past, Hero Arts colors were exclusive for a fixed period of time, and thus the original Shadow Ink colors (from many years ago) after two years became available as Memories Ink Pads. More recently, with the release of new Shadow Ink, Mid-Tone Shadow Ink, and our newest Neon Inks, these colors are exclusive to Hero Arts going forward.
I hope that helps! Happy stamping!

Thanks so much for the info, Tami!
