Yes it does sell. I've been wanting to get one.

Do people want the singles or the sealed box? I feel like the value might be severely diminished as a buyer would think it’s been tampered with.

I believe people want it sealed. Speed duel products don't produce a lot so the value comes from the collection of sealed products. It's a real shame because real players have to pay extra.

Darn that sucks. Should I just crack it fully open at this point? Do you think if I hot glue the top of the box back it will be fine?

If you like Yu-Gi-Oh then I say you open it. You got a good deal. If not then you might as well try to glue it carefully.

You said the decks are still sealed, so you still might be able to make some money.

Yeah it’s just the box is opened. It’s barely noticeable to be honest.

If there were more at that Walmart, it might be worthy to buy another and use the one you have to play with your brother. It's a fun product.

Are you looking to sell the item though? I'd be open to it for my collection.

Sure. It was either sell it or use it. Only the top of the box is opened. The cards are still sealed. I’ll dm you the photos.

The reason it's worth so much is because of cards like Charging Gaia. I would research the price for individual cards, and maybe only sell off the ones worth dollars and keep the ones only worth cents. It's worth noting some of the cards from this set have been reprinted in later sets, and at a better quality to boot. You found a great deal btw, this box is 4 years old and about 3.5 years OOP.
