Gifts for Your Sister or Best Friend
You know her better than almost anyone, which somehow makes buying for her harder. Here are ideas that fit how she actually lives, from small treats to one gift she'll wear every day.
The gift she'll wear every day: a smart ring ($79.99)
If she's always tired, always busy, or curious about her sleep, the Odessa smart ring is a thoughtful pick. It looks like jewelry and has no screen. In a free iOS/Android app it tracks sleep, heart rate, blood oxygen, skin temperature, stress and steps, plus cycle tracking, with no subscription. It's 5ATM water resistant, the battery lasts 5–7 days, and it comes in silver, black, pink or gold, sizes 6–14.
Gift-friendly details: a 60-day trial (worn rings accepted; change-of-mind return postage is paid by the customer) and free size swaps, where the new size ships first. $79.99. See the ring →
Not sure of her size? Here's how to find her ring size secretly, or use the ring sizer.
For the sister who never sleeps enough
- Weighted sleep mask ($29.99): soft, contoured blackout cups for naps and travel.
- Sunrise alarm clock ($44.99): brightens gradually before her alarm, for dark winter mornings.
- Bluetooth sleep headband ($39.99): thin speakers in a soft headband for podcasts in bed.
For the best friend who's always travelling
A ring travel case ($24.99) keeps her rings safe in her bag, and it doubles as a pretty way to present a ring.
