The Christmas edition of Trader Joe's Fearless Flyer came out today, with lots of the products having really weird looking Customary net contents. Of course, reality is that they are imported and the net contents look more sensible in metric. I picked some examples where I could verify the dual net contents declaration in the product photo since the prosy description is pure Customary. Too many to post photo links, but you can search for the official product names below (all Trader Joe's) if you really want. Just the name and net contents:

Hot Cocoa Ornaments, 10.58 OZ (300 g)

Belgian Cookie Collection, 35.2 OZ (1 kg)

Sparkling Pomegranate Punch, 8.45 FL OZ (250 mL)

Truffle Powder Seasoning, 0.88 OZ (25 g)

Cookie Mug Hangers, 5.47OZ (155 g)

Decked Out Tree Cookies, 7.05 OZ (200 g)

Vegan Mint & Chip Bon Bons 5.46 OZ (160 g)

Dark Chocolate Sea Salt Caramel Gift Card Holder 2.1 OZ (60 g)

Sugar Plum Sparkling Beverage 25.4 FL OZ (750 mL)

This last one is a non-alcoholic substitute for sparkling wine and the only one where the size is described as 750 mL bottle, probably because all their wines are described by metric contents (US law).
