What to know before buying
Listing details to confirm
The listing is inconsistent about material, describing the folder as vegan leather in its title and features but as leather in the product description. Dimensions also differ: package dimensions are 34.29 x 25.9 x 4.9 cm, while the description gives 35*25.5cm closed and 35*54cm open. The 175-sheet capacity and 13-inch tablet accommodation are listing claims. Confirm the material and fit details before buying.
Who is it for?
A good fit for
- People who want a single folder for meeting notes, loose documents and basic calculations.
- Students and professionals carrying A4 paperwork and a tablet-sized device.
Less suited to
- Buyers who need confirmed genuine or vegan material, or precise verified dimensions before purchase.
- Anyone needing a confirmed tablet fit beyond the listing’s stated 13-inch compartment claim.

The supplied evidence contains aggregate star ratings but no written customer feedback. The distribution is predominantly five-star, with a small share of four- and three-star ratings. This offers limited reassurance about reported satisfaction, but it does not identify what customers liked or disliked, nor confirm the folder’s claimed capacity, fit or material.
Frequently asked questions
What does the AOOSU folder include?
The listing describes a built-in calculator, a 25-page notepad and 10 transparent document sleeves. The product-description package list also names a calculator, notepad and document bags, but check the selected listing because its wording differs elsewhere.
How much paper can the rings hold?
The listing claims the one-inch rings hold 175 sheets. Treat this as a stated capacity rather than an independently confirmed measurement.
Will it fit a 13-inch tablet?
The feature text says a divider can accommodate a 13-inch tablet. It does not provide the compartment’s exact measurements, so check device dimensions against the seller’s details.
Is the folder vegan leather?
The title and feature text call it vegan leather, but the product description says leather. The material is therefore unclear in the supplied listing, so confirm it before ordering.
