50 x Mini Large Letter Cardboard Postal Mailing PiP Boxes ~ 101mm x 101mm x 20mm (4'' x 4'' x 0.8'')

These are quick to assemble, however they are quite flimsy (ie sometimes the card bends in the wrong place rather than the pre-folded edges) and some of the ones I received did not contain the “wall” filling throughout (see pic - the flap is just made from thin paper!) and therefore would not stay together. Would have preferred to contact directly rather than leaving a bad review but no option to do so! 🤷🏼‍♀️

They work great. Every time, the person at the post office puts it through the little measurement thingie. Every time, it fits. no problem.

Very good and thick, easy to assemble. Will recommend.

Nice small item doesn’t take up space. Functional.

Great quality

bought these by mistake as usually bought the larger size but nice quality, lightweight postal boxes for small items,

good boxes, wasnt to impressed at first as they dont all fit correctly, not cut probably, but the ones that are , they are good.

Will order more just the right size and good quailty
