b.box: what it’s actually made from

We have scored 3 b.box products. They average 49.3 out of 100 on materials, and the spread between the best and worst is 53 points.

Of those 3: 1 name the surface that touches food at least to a material family; 0 state a country of manufacture; 1 have a materials claim backed by anything other than the maker’s own word.

That spread is the thing worth noticing. The same company publishes enough about b.box 500ml Insulated Bottle with Silicone Spout for it to score 83, and so little about b.box Bento Lunch Box 2L that it scores 30. Disclosure here is a per-product decision, not a house style.

b.box Bento Lunch Box 2L · AU	Lunchboxes	30	Polypropylene container · silicone seals · no grade or standard named for either

Where these sit on the site

b.box appears in Bottles · Lunchboxes. The Australian and American editions are scored the same way, so a product marked AU and one marked US are directly comparable.
