What to know before buying

Listing details to confirm

Customer feedback says capacity experiences vary, with some finding it spacious and another reporting it was insufficient for a year's bills. Feedback also reports that label stickers may not adhere well or can fall off. The listing specifies A4 paper, while its title also says A4 Letter Size, so confirm fit for your intended paper size. Capacity is stated as 360 sheets in one listing detail and up to 360 pages in another, and the feature copy describes the material as water-resistant while an A+ heading calls it waterproof. Treat these as listing claims rather than verified performance.

Who is it for?

A good fit for

People sorting A4 paperwork such as bills, invoices, school papers, or receipts into separate sections.
Users who want a compact document organizer with a closure and small-item pockets.

Less suited to

Buyers who need confirmed compatibility with US Letter paper, since A4 is the specified supported size and fit for Letter is not established.
Anyone relying on reliably adhesive labels or needing a confirmed capacity for a full year's paperwork.

Customer feedback highlights ease of organization and use, with positive remarks about color and perceived value. Capacity impressions are mixed, and reports about labels falling off are a practical concern if you plan to depend on the supplied label stickers. The listing's 13 pockets and claimed 360-sheet capacity offer a framework for sorting documents, but neither resolves whether the folder is large enough for a particular workload.

Frequently asked questions

How many sections does the folder have?

The listing specifies 13 pockets, with top-positioned tabs and label inserts described for organizing them.

Does it fit US Letter paper?

A4 is the stated supported paper size. Although the title mentions Letter size, the listing does not clearly establish Letter compatibility, so confirm the fit before buying.

How much paper can it hold?

The listed fastener capacity is 360 sheets. Other listing copy says up to 360 pages, so treat the capacity as a manufacturer claim rather than a verified measurement.

Are labels, a pen, and business cards included?

The listing describes label inserts, a pen pocket, and a business-card slot, but does not establish that a pen or business cards are included.
