What We Found in an Amazon Mystery Box: Birkenstock & More — May 24, 2026

Twenty-six items, just under $600 in retail value, and honestly a pretty solid spread for a Tuesday in Hot Springs. This Amazon Mystery Box closed on May 24th and our team cracked it open this afternoon. The range was all over the place — sandals, supplements, energy drinks, a collagen formula, and yes, two tubes of caulk. We love when a box keeps us guessing.

The Star of the Box: Three Pairs of Birkenstock Mayari 071791 Size 35/L4-4.5 R Birko-Flor Black Sandals

Three sealed pairs at $100 each — that's $300 in Birkenstocks alone, straight out of one box. Size 35, Birko-Flor, classic black. These went straight to the floor and we don't expect them to last long.

The supplement haul was surprisingly deep. Six sealed bottles of Super Beta Prostate Advanced Prostate Supplement for Men at $31.99 each — 60 caplets per bottle, beta sitosterol formula. That's nearly $192 in one product category alone. Solid value if that's something on your shopping list.

We also pulled two boxes of CELSIUS Dragonfruit Lime On The Go Energy Drink Mix - 14pk Sticks — grab-and-go packets, great for the gym bag. One bottle of Rejuvicare Liquid Collagen Beauty Formula with Amino Acids, Protein and Biotin, Delicious Grape Flavor rounded out the wellness side of things — 32 servings, grape flavor, sealed.

Then there were two tubes of DAP Alex Plus 10.1 oz White All Purpose Acrylic Latex Caulk Plus Silicone. Not glamorous. But hey, somebody out there always needs caulk. Plus dozens more bin-labeled items heading to our store bins — stop by and dig through those too.
