Maxi 6, Mini 6 and Cleanafeeda are manufactured in tough polypropylene and the injection moulding process will always produce manufacturing 'marks' on the polished surface.
However, some products have additional marks from the handling and stacking process following manufacture. These products are functionally no different from others but if they have a few more ‘cosmetic’ marks on them we consider them slight seconds.
Maxi 4, Mini 4, Micro 3 are manufactured in ABS plastic by vacuum forming. These items rarely have any cosmetic defects but if they do, we consider them to be ‘slight seconds’.
Like all other products, their functionality is not impaired at all.
