I have just received a 3 set pack of Ernie Ball Super Slinky 9"s & a 3 set pack of Regular Slinky 10"s.
I have never had 3 packs before just single set packs so don"t have any 3 set packs to compare them with.
What I can see is that the pink colour of the 9"s pack is a lighter pink than a single set pack & the green 10"s pack is also lighter & less "shiny" than a single pack.
Also on the individual paper envelopes the strings are in the red printing is lighter on the triple pack envelopes ?
These have come from an ebay seller with 99.9% positive feedback & the only negative feedback they have received really is the delivery times being longer than advertised, although mine came on time.

I also once bought a fake microphone from eBay. I knew the second I opened the package it was fake because I had the real version before but if I didn't, it probably wouldn't have crossed my mind that it was fake. The seller claimed he had thought it was real the whole time he had it and I believe that's possible if he'd never seen a real one.
I only use eBay for things that can't be faked, like if it's not a brand name item anyway.
They were £15 per 3 pack as opposed to £8 for a single pack from my nearest music store.
If the price on eBay was lower than any shop offered I'd start to be suspicious there. In your case it's only a few pounds less but still, the con artists selling fakes would be greedy and charge close to the real price anyway.
If they're real I'd wonder how a small time eBay person could undercut massive global companies like Amazon who sell in mass.
The strings may well be genuine it is just that my suspicions were aroused by the slightly different packaging colours compared to the single set packs I am used to.
I'd think Modulus_Amps would likely be right that the person has either got them for cheap at something like a liquidation auction - so they're real but he can sell them for cheap - or that they're fake so don't cost him much anyway.
With the microphone I mentioned, there was a big weight difference right away which rang alarm bells then I found online ways to look at the internal wiring that indicates fakes. With guitar strings there really isn't much to them so not sure there necessarily would be any way to tell they're fake.
You could just try them and if they sound normal, take a chance and hope they don't break during a gig. I'd personally send them back and not risk it for the sake of 1 pound per pack.

But I have here 2 sets of Eb super slinkys, 3 sets of hybrid slinkys.
All bought individually either from Pmt, or strings direct.
I've noticed lately that some packs now have the shiny exterior, like a metallic foil look. Others still have the same non shiny pack.
Over the years I've also noticed slight differences in colour on the external packs. Some slightly different shades of pink than others, but I noticed that on the non shiny packs more so.
I would presume being bought from SD or PMT means these are genuine every time. So I'd say some colour variations are normal across the board.
Thing is, lots of people claim EB strings can be hit and miss in terms of quality, though I've never really found it.
Maybe one or two packs over the years have felt slightly different, I presume old and degraded despite the foil.
I don't think EB have a fake checker like D'adds do, but maybe give them an Email and see if they can suggest any pointers.
Ultimately, if you buy from tax-dodging multinationals, the non-tax dodgers won't survive, the tax dodgers prices will then rise, and the government will still have to raise the same level of tax, so you'll end up paying that too - life will end up more expensive in the long run... Unless you happen to live in Luxembourg.
