What to know before buying
- The listing gives the colour as both “Pastel” in the title and “Black” in the details and five-pack description. Confirm the selected variant’s colour before ordering. The listed dimensions and weight are presented together as “5 x 4.5 x 12 cm; 1.51 kg” and should not be treated as verified measurements. Claims of bleed-free writing and suitability for fountain pens are listing claims, not independently verified performance.

- Anyone wanting several A5 notebooks with tear-out sheets and a pocket for loose materials.

Aggregate ratings lean positive overall, but a notable share are one-star ratings, so the feedback is not uniformly favourable. Without customer comments, the ratings do not explain the reasons behind either response. For buyers, this is a limited signal alongside the listing’s specific claims about paper, binding and colour, which are not confirmed by rating figures alone.
