Which version do you have?

For the cheapest way to own Muk #31, grab the Standard version for $1. The Reverse Holo version at $5 offers a slight aesthetic upgrade, indicating a different print run or finish, but the difference in value is minimal. If budget is the primary concern, buy the Standard. If you want a slightly more visually distinct piece, the Reverse Holo is a small step up in presentation.
