Review: Small but classy - Nice lunchboxes, and quite good quality for the price. I like the various compartments, but the boxes are quite small and you'll have to do some geometry to get a standard UK sandwich to fit in it. More suited to pasta, rice, fruit... that sort of thing. The provided band keeps everything together and it certainly looks very impressive. Should keep your food insulated and it should not leak out. Overall I would recommend, as they have good functionality, but just be careful about the sizing to avoid disappointment.
Review: Bento box for lunch - I've purchased this for my Son this Christmas, not a particularly exciting gift but one that was needed so I bought it whilst it was on an offer. There's a whole array of bento boxes but this one has the added practicality of being able to remove the dividers if you want a bigger portion. The boxes have a classic bent style to them, smooth and sleek, lids seem to fit well and the strap is a nice touch in keeping items secure. Yet to use so can't comment on usage yet. Overall for the price (I paid approximately £10.50 on special offer in October) its a handy item and the quality seems very good.

A: No, it can't

**Q: Hello, Is the colour matte black or gloss black  (does the surface reflect light)?**

### ⭐⭐⭐⭐ Nice box but may be too small for some
*by L***N on 20 March 2026*

Nice lunchbox and good size. The only downside for me is that one tub is not as deep as the other so I couldn’t fit a yoghurt in one and sandwich in the other.
