We are a small shop, so we cannot list everything – which turns out to be the useful constraint. Here is what a mug has to clear before it goes on the site.
It has to have a traceable source
We buy from manufacturers and from established US distributors, and every purchase is invoiced. If a supplier cannot tell us where the goods came from, we do not buy them. This rules out a great deal of very cheap stock, and it is the single most effective thing we do to keep counterfeits out.
It has to have a GTIN
Every product we list carries the manufacturer’s barcode, and we check the barcode on the arriving goods against the one on the purchase order. A GTIN is what lets you verify a product independently of anything we say about it, so we treat “no GTIN” as “no listing”.
It cannot be licensed character merchandise
We do not stock mugs bearing film, television, sports-league or cartoon licensing. That category carries most of the counterfeit drinkware in circulation, and verifying a licence chain properly is beyond what a shop our size can do. Staying out of it entirely is the honest option.
It has to survive the bench
Incoming stock is opened and checked: rim and foot for chips, glaze for hairline cracks, handle seating, and on travel mugs, whether the lid actually seals when the mug is upside down. Failures go back to the supplier.
The specification has to match the listing
The most common problem is not a faulty mug – it is a supplier quietly changing a pack size or a capacity between production runs. We check capacity, colour and pack count against the listing every time stock arrives, and we update the page rather than shipping something that does not match.
Why any of this matters to you
Because it is why the delivery estimate on this site is a promise rather than a hope. We hold the stock, we have looked at it, and we know it is the item on the page. There is no drop-shipper in the middle deciding what you actually get.
