Packing shipping supplies can look interchangeable until the job calls for a particular format. A white rigid mailer, a #10 business envelope, and a brown catalog envelope serve different kinds of paperwork. The clearest choice starts with what you are sending, then considers pack quantity, color, and listed price.
Quick take
The 100 Pack White Rigid Mailers is the option for a larger mailer requirement. Yeplan 60PCS #10 Envelopes is geared toward standard business correspondence, including letters, invoices, checks, and documents. The two FloraSea catalog-envelope packs fit mailings and organization jobs involving papers, brochures, booklets, and similar flat contents. Among the listed prices, Yeplan is the lowest, while the 100-pack rigid-mailer option is the highest.

Product notes
100-Pack White Rigid Mailers
Choose the 100 Pack White Rigid Mailers when the mailing task calls for a white, rectangular rigid-mailer format and a substantial quantity. The description names documents, photos, letters, books, magazines, and crafts among its intended contents, while the long-side opening and self-sealing tear-tape design keep the closure approach straightforward. At USD 41.57, it is the highest-listed option in this group, which is the main tradeoff. It is also a distinct format from the #10 business envelopes and brown catalog envelopes, so its fit depends on needing the rigid-mailer style rather than conventional paper envelopes.
Yeplan 60PCS #10 Envelopes
Yeplan 60PCS #10 Envelopes is the direct pick for letter-size business correspondence. The white, no-window format is paired with a self-seal closure, and the description specifies 24LB paper, a blue security-tint pattern, and dimensions of 4-1/8 by 9-1/2 inches. Its USD 8.49 listed price is the lowest here, while the 60-envelope quantity offers a middle ground between the two catalog-envelope packs and the rigid-mailer carton. The limitation is format: #10 envelopes are designed around standard letters, invoices, checks, and documents rather than the broader catalog-envelope shape used by the FloraSea options.
FloraSea 25 Pack 9 x 12 Catalog Mailing Envelopes (P3)
The FloraSea P3 pack makes sense for brown kraft mailings that involve catalogs, important papers, business documents, brochures, booklets, receipts, magazines, or photos. It contains 25 rectangular 9 x 12 catalog envelopes and uses a Release & Seal peel strip, so the closure does not require moisture. The brown manilla presentation is also suited to home, office, business, and school organization tasks named in its details. Its limitation is the smaller 25-envelope pack quantity. At USD 9.26, P3 is listed USD 0.22 above the other FloraSea catalog-envelope option.
FloraSea 25 Pack 9 x 12 Catalog Mailing Envelopes (P4)
FloraSea P4 is the straightforward choice when a 9 x 12 brown kraft manilla catalog envelope is needed and the lower listed price between the two FloraSea versions matters. The pack includes 25 self-sealing envelopes with a pre-folded closure and peel-strip design. Its description also calls out mailing and storing paperwork, brochures, booklets, receipts, magazines, and photos, giving it a broad paper-handling role for home, office, business, or school work. The limitation is that the listed package remains a 25-pack, so it is a different quantity proposition from Yeplan's 60 envelopes or the 100-pack rigid-mailer format.
Final recommendation by use case
Choose the 100-Pack White Rigid Mailers for a larger white rigid-mailer requirement. Choose Yeplan 60PCS #10 Envelopes for standard letter-style correspondence with a windowless business format. For brown catalog-envelope tasks, choose FloraSea P4 when the lower listed price within the FloraSea pair is the deciding factor. Choose FloraSea P3 when its stated catalog, brochure, booklet, and storage uses most closely match the mailing or organization job at hand.
