First of all
their stock isn't as large as you think. Ever-Wish doesn't actually remove products from their site when they run out of stock, even when they're not realistically going to get more. This heavily inflates the store page/catalogue with items that will never be purchasable again, including quite a lot of MFB products and older Burst products. If you hover your cursor over an item and don't get an "add to cart" option, they're out of stock and you won't be able to buy it from there. Add onto that the fact that most items are on the site
twice due to having a second listing for wholesale pricing and you start to realize just how much excess bloat there is on the site in these older products.
Just for the sake of example, if you search "metal face" you'll get an entire page dedicated to just metal face bolts and metal stone face bolts, but only the BB-36 unpainted metal face bolt set at standard pricing actually has any stock on the entire 12 item first page from this search, and there's only 7 unique items as only the two Metal Stone Face sets for some reason have their wholesale listings on the second page. You literally get 11 dud items there, which is one of the things that honestly bothers me about the site as it makes searching for in-stock items vastly more irritating by needing to hover over every single listing to tell.
Secondly, I've bought out quite a few of those older MFB boosters with only one item of stock left fairly recently, and not a single item was a midfake. Not a one! No, I have to side with Shindog here about the accuracy of these things, and what few things they do have left from the Metal Fight era seem to beold stock they never managed to get rid of, unlike the more common sites scrambling to maintain stock and getting midfakes from their suppliers to cover the excess need. Burst has similarly never gotten fake stock as far as I'm aware, as they seem to get stock before any fakes can replicate the TT products.
tl;dr Their catalogue is vastly bigger than their stock, but what they have is definitely real.
