KPop Demon Hunters Backpacks: 7 picks from $20.49

The cheapest thing on this page, at $20.49, is the Get Trend Windproof Travel Umbrella, and it is not a backpack. Its title mentions fitting a backpack, which is how it landed among them. The least expensive bag is the Vanilla Underground pink one at $26.00, against $49.99 for the Manotears commuter bag.

Size is where these separate. Get Trend states 18in, TripPal states 17 inch, and both AI ACCESSORY INNOVATIONS bags state 16". Two inches decides whether a folder stands up inside or bends, so measure the binder your kid actually carries and choose from the stated numbers. Vanilla Underground calls its bag a school book bag and Manotears calls its own large capacity for travel and commuting, but neither title puts a figure on it, and the seller's page is where you would have to look, because that measurement is not here.

The two AI ACCESSORY INNOVATIONS entries are two different bags, not a duplicate: the same 16" size, but one carries a rubber molded bag charm at $42.99 and the other is an allover print at $39.99, so the charm accounts for the $3. Those are also the only two titles that name Rumi, Zoey and Mira; the Get Trend bag says Huntrix, and the Vanilla Underground one names no character. TripPal's entry says 3PCS and spells its color "bule" without saying what the other two pieces are, so ask that seller what comes in the box before you spend $39.99 there.
