Customer Reviews
Good products, slow delivery
I bought an Insulated Food Jar and a Mini Lunchbox. The product quality is definitely there, they feel robust and the food jar kept my son's lunch warm for school. However, shipping took a full 8 days to get to me, which felt a bit long compared to other online stores. Customer service was polite when I inquired about the delay, but couldn't speed things up. Overall, I'm happy with the items, just wish delivery was a little faster. Value for money is fair, considering the durability.
Great sippy cup, good shipping
I ordered a Weighted Straw Sippy Cup for my toddler. The ordering process was straightforward on their website, no issues there. It took about 6 days to arrive in Ohio, which felt reasonable. The cup itself is fantastic; it really is leakproof, even when my kiddo throws it around. Cleaning the weighted straw takes a bit of effort but the included brush helps a lot. The quality feels sturdy, like it will last. Support wasn't needed, everything arrived perfectly.
Reliable lunchbox, good experience again
This was my third order from b.box, I got a Lunchbox this time for my older child. I've bought sippy cups and snackboxes before. Their products are consistently good, always holding up well to daily use and dishwasher cycles. This lunchbox is just as reliable as my previous items. Shipping was quick this time, reached me in 4 days. It's why I keep coming back, I know what I'm getting.
Good sippy cup, easy to clean
I bought a Weighted Straw Sippy Cup. It doesn't leak. Easy for my toddler to use. Dishwasher safe, which is important. Happy with the purchase.
Nice products, decent value
I was looking for a good deal on a new lunchbox for my daughter and decided to try b.box after seeing their Back to School sale. I picked up a Lunchbox and a Tritan Drink Bottle. The sale price made it feel like a good purchase. Shipping was free because my order was over $50, which helped with the budget. Everything arrived safely. The lunchbox has separate compartments which is handy. Overall, I feel like I got good value for what I paid.
B Box Community Discussion
Share tips, ask questions & help fellow shoppers save more
Are the bbox products actually BPA free and all that good stuff? Or is it just marketing speak? Trying to be careful with what my baby eats out of.
Hey guys, thinking about getting one of those bbox lunchboxes for my preschooler. How's the leakproof situation really? Some brands claim it but then stuff spills everywhere.
Anyone know how long shipping takes to like, California? Need a new sippy cup kinda urgently before a trip next month.
Quick question about the new customer discount, can I use that 10% off on a bundle, like one of the school packs? Or is it only for full-price individual items?
How do these compare to like, Bentgo or Yumbox? Specifically the lunchboxes. Are they worth the slightly higher price point?
