What We Found in an Amazon Mystery Box: Flutter Valve & More — May 29, 2026

This one was a mixed bag in the best literal sense. Not a jaw-dropper on retail value — $436.92 total with a healthy chunk heading to our bins — but the individual finds were genuinely eclectic, and Hot Springs shoppers are going to have opinions about some of these.

Twenty-Two HAKADASU Thank You Card Set Navy Blue (15 Cards) Packs. Yes, Twenty-Two.

That's the wildest part of this box. Twenty-two sealed packs of HAKADASU Thank You Card Set Navy Blue (15 Cards) at $4.50 each. That's $99 in greeting cards alone. Whether you're running a small business, planning a wedding, or just wildly optimistic about your future thank-you note output — we've got you covered.

Beyond the card avalanche, the box got interesting fast. A Ceiling Punch Bag Adult Stress Relief came out sealed and ready to hang. At $24.99 retail, it's a legitimate stress tool that mounts to your ceiling. No gym required. We also pulled a Flutter Valve Natural Breathing Exerciser Device with 3 Ball Resistance Levels — $29.99 retail, designed for respiratory training. Unusual find. Solid one.

Two Wooden Yarn Bowl with Spiral Design pieces came out together, $15.99 each. If you knit or crochet, you know exactly what these are for. If you don't, they're also just genuinely pretty on a shelf. Three packs of Baby Protection Accessories Adjustable Strap Drawer Safety Lock Child Proof Cabinet Latch Pack of 6 rounded things out at $12.99 each — practical, sealed, six latches per pack.

We also grabbed a pack of 300 PCS Stickers Aesthetic Literary Stickers ($8.99) that's going to make some sticker-obsessed customer very happy. Plus dozens more bin-labeled items heading to our store bins.

Not every Amazon Mystery Box is going to hand you a drone or a power tool. Sometimes you get a ceiling punch bag, a breathing exerciser, and enough thank-you cards to outlast several lifetimes of gratitude. This one was mid-range in value and maximum in randomness — and that's kind of the whole point.
