Here's a small, thoughtful detail on ski accessory manufacturer Yardsale's poles: They contain embedded magnets, making a pair of them easier to carry.

Their P1 Poles, aimed at the casual skier, run $149 and are available in several different fixed lengths.

Their $189 P2 Poles feature longer grips and are aimed at backcountry skiers. The handles feature a button that allows you to adjust the shaft length.

After posting their invention on TikTok, company founders Kelly McGee and Cristina Asbaugh drew the attention of "Shark Tank's" producers and were invited onto the show. They secured $250,000 in funding from guest shark Kendra Scott, in exchange for 10% equity and a $5 royalty per unit sold, until Scott recouped $300,000.
