We’ve all heard of the famous Stanley cup, but why is it such a big deal?

The hype over the Stanley cup (also known as the Stanley Quencher tumbler) is similar to when Yeti tumblers were all the rage, except this time, the Stanley cup that everyone obsesses over is able to hold a whopping 40 ounces of liquid. The cute selection of colors is just the cherry on top.

However, the main reason this particular brand became popular was simply through influencers on social media platforms, especially Tik Tok.

Those of us who love the idea of an insulated cup that holds that much liquid, however, do not need to pay $40-$50 for the brand. Instead, a knock-off that does the exact same thing for about half the price will satisfy.

For that very reason, we’ve selected our favorite Stanley Quencher dupes that are still functional and stylish, but at a much more reasonable price.

These are our top 10 picks under $30 we think you’ll love.
