Water Bottle

My son absolutely loves this water bottle. He’s taken it to school everyday for weeks and it still looks new.

Angela (Auckland, NZ)
Great size

Since this has arrived I’ve used it every day for coffee and teas. It’s a good size and love how there are no leaks if the lid is put on tight.

Kathryn (Auckland, NZ)
A great little bottle!

I'm very picky about my child's water bottle because so many of them are impossible to thoroughly clean, but this water bottle is great! It is lightweight and small enough for little hands to happily hold, and the lid is super easy to clean thoroughly, with no hidden inaccessible bits you cannot get to. I also love that you can get different styles of tops (it came with a straw top and I also got a screw top). Highly recommend!

Corina (Christchurch, NZ)
Another awesome addition to our Bento Ninja collection

We already knew how awesome these bottles were as you’ll see from the picture below. The latest one (blue) is for my 18 month old who was very happy to get his own big boy bottle. Bonus is when he needs to upgrade to a bigger one in a few years, we’ll buy the Flip lid so this one can become a takeaway coffee cup

"FOREVER PEGS®" Ultimate Peg Pack
Meli Stewart (Auckland, NZ)

Such great pegs, I love these. Who’d have thought pegs could be exciting? But they are. Nice feel to them, perfect springiness and love that there are different sizes. Great product!

Sleek and effective!

I having been using my squeegee for a couple of weeks now and am loving it! It is high quality and looks so much nicer than any plastic squeegees, and works amazingly too. Highly recommend!


I like everything about these chopsticks. They aren’t slippery so they’re really easy to use, they’re solid, high quality and beautiful. I bought the multi colored set, but my children fought over the rainbow ones, so I bought an extra set of rainbows too. 🤪 I also bought a set to gift and I will definitely be ordering more. They’re a quality gift that you can be proud to give.
