Both options here are white #10-style business envelopes with self-seal closures and internal security designs. The meaningful split is the listed pack quantity and price.

Where each envelope pack fits best
Yeplan 60PCS #10 Envelopes works for smaller mail runs
The Yeplan pack is the clearer match for an office task, household mailing project, or correspondence run that does not call for a larger envelope quantity. Its no-window design suits letters, invoices, checks, and documents where you want the outside of the envelope left blank. The stated 24LB white paper and blue security tint pattern are useful details for shoppers specifically looking for those described construction features.
120 Count Business Envelopes #10 works for higher volume
The 120-count pack makes sense when you would rather begin with more envelopes for ongoing business correspondence. It retains the shared basics: a white, rectangular, no-window #10 format and a self-seal closure. Its product description specifically identifies a security pattern inside and privacy protection, making it a fitting choice for mail that benefits from an interior pattern.
Product notes
Yeplan 60PCS #10 Envelopes Letter Size Self Seal Business Envelopes No Window
Choose this Yeplan pack for its straightforward 60-envelope quantity, no-window layout, and described blue security tint pattern. The self-adhesive strip is intended for sealing letters, invoices, checks, or documents without separately moistening an envelope flap. Its white 24LB paper is another stated detail that may matter if paper weight is part of your envelope selection. This is a focused option for professional or everyday correspondence that needs a blank exterior. The tradeoff is quantity: it contains 60 envelopes, while the other comparison option is configured as a 120-count pack. It is therefore better aligned with a contained mailing need than a larger recurring correspondence supply.
Envelopes Letter Size, 120 Count Business Envelopes #10, Self-Seal Security
This 120-count envelope pack is the choice for shoppers who want a larger supply in one format. It is described as a white, rectangular, no-window #10 envelope for business correspondence, with a self-seal closure and a security pattern inside. Those details make the format suitable for letters and office mail where an interior pattern is desired. The concrete reason to choose it is its 120-envelope count, which provides more envelopes than the Yeplan pack. Its limitation is that the larger quantity may be unnecessary for a small, one-time mailing task; a shopper with a more limited envelope need may prefer the smaller Yeplan configuration instead.
Final choice by use case
For a smaller batch of letters, invoices, checks, or documents, choose Yeplan 60PCS #10 Envelopes Letter Size Self Seal Business Envelopes No Window. For repeated business correspondence or a larger on-hand envelope supply, choose Envelopes Letter Size, 120 Count Business Envelopes #10, Self-Seal Security. Both keep the core no-window, white, self-sealing business-envelope format, so the final decision is chiefly about the quantity you want and the listed price you are comfortable paying.
