Absolutely excellent definitely going to buy again

### ⭐⭐⭐⭐⭐ Great product
*by T***. on 13 December 2025*

Yes, excellent. Will buy again and the smaller size too

### ⭐⭐⭐⭐ Ok boxes, but flimsy.
*by M***A on 4 June 2025*

The size is accurate & the folds were ok on the boxes I received - they were delivered well packaged and quickly! However, I won’t be buying again due to the thinness of the cardboard. They are very flimsy! They are ok for the money paid though.
