Hi,

I have recently purchased 2 batches of Mega Dream Ex sealed booster boxes, some of them from Ebay (£80 each) and some from an online retailer (£99 each).

I strongly believe the ones from ebay are resealed, even though the seller seems to be claiming otherwise, they argue that they supply many TCG shops and nobody has ever come back with a negative concern of this sort. I want to make it clear that I am not claiming the seller was the one resealing the products.

Here's the picture, the right one is from the online retailer and I can clearly see some characteristics that make me believe the one on the left has been resealed, for instance the pattern the packaging displays when the back (or front) is hit by a UV light.

Other things I noticed:

\- the right (real) has one side with no seal line, while the left has a seal line on each side

\- the right (real) has a curved sealed line, while the left are mostly straight.

\- the right (real) weighs 185.12g, while the left weighs 187.64g (i.e. +2.52g)

The last point about the weight is interesting, just watched this video ([https://www.youtube.com/watch?v=RAW20OTVUxI](https://www.youtube.com/watch?v=RAW20OTVUxI)) and after weighing 20 boxes the heaviest was 186.1, so 187.64 is suspicious.

I have other japanese sealed booster boxes (e.g. terestal festival, glory of team rocket, etc), and they all present the same packaging pattern when exposed to UV light, but the box on the left doesn't seem to have that.

I have opened both and found the following differences:

\- The pull rate seems to be legit 9 RR, 3 AR, 1 MA and 1 SR (Non support) BUT ... I the RR had quite few duplicates, 3 Fezandipiti + 2 Latias. While the pull rate on the left one had 0 duplicates.

\- The empty box for the left, weighted 22.00g, while the right (legit) weighted 20.25.

\- The UV light test against the unsealed boxes shows the same differences as when sealed, so the grainy texture is from the box, not the seal.

\- The strip to open the box is also different, the left one was harder to "pick and pull" and when pulled, it also stripped away the bottom half that was supposed to stay glued on the box. While opening the left (legit) box was easy, pulled straightaway and the bottom half remained attached to the box no prob.

\- Touching surfaces of both boxes has a very subtle diff, is very subtle, but the legit one feels more "glossy" at the touch (it's hard to explain), again very subtle to feel the diff.

\- The "MEGA" logo in the packs is slightly offset when compared to the legit one.

Mega Dream Ex Box Legit or Not?
