Quick verdict
The key choice in packing and shipping is whether you need a larger envelope quantity for ongoing correspondence or a smaller pack with a lower listed price. Both options are white, rectangular #10 no-window envelopes with self-seal closures, so the decision comes down to pack size, price, and the stated inner privacy design.
Choose 120-Count #10 Self-Seal Security Envelopes when a 120-envelope quantity fits your mailing routine and you want the stated security pattern inside with privacy protection. Choose Yeplan 60PCS #10 Envelopes Letter Size Self Seal Business Envelopes No Window when a 60-envelope quantity is enough, the USD 8.49 listed price is the better fit, and its stated 24LB white paper and blue security tint are priorities. The listed-price gap is USD 14.74.

Where each envelope pack fits best
120-Count #10 Self-Seal Security Envelopes is the clearer pick for someone organizing a more substantial run of business correspondence. Its larger count is the meaningful distinction between two otherwise closely matched formats. The description also calls out a security pattern inside and privacy protection, useful details for mail that should not reveal its contents through the envelope.
Yeplan 60PCS #10 Envelopes is the better match for letters, invoices, checks, or documents when a smaller quantity is more practical. It shares the no-window, self-seal design, while adding a stated blue security tint pattern and 24LB white paper. Its listed price is lower, though it contains fewer envelopes than the 120-count pack.
Product notes
120-Count #10 Self-Seal Security Envelopes
Pick this pack when you want a single order of 120 white #10 envelopes for business correspondence. The 4 1/8 by 9 1/2-inch no-window format, rectangular shape, and self-seal closure create a straightforward option for routine letter mail. Its named interior security pattern and privacy protection give it a clear role for correspondence where concealing the contents matters. The larger quantity makes sense when you expect to use envelopes regularly rather than occasionally. The main limitation is its USD 23.23 listed price, which is higher than Yeplan's listed price. It also does not change the basic format: it remains a white, no-window #10 envelope.
Yeplan 60PCS #10 Envelopes Letter Size Self Seal Business Envelopes No Window
Yeplan's envelope pack suits smaller batches of professional or personal mail where 60 envelopes cover the task at hand. It combines a self-seal strip with a windowless design and a blue security tint pattern intended to shield sensitive letter contents. The description specifically names letters, invoices, checks, and documents as uses, while the stated 24LB white paper is a useful material detail for shoppers comparing paper specifications. At USD 8.49, it has the lower listed price in this comparison. Its limitation is the 60-envelope quantity: shoppers planning a larger correspondence run may prefer the 120-count envelope pack instead.
Final choice by use case
Choose 120-Count #10 Self-Seal Security Envelopes for recurring business correspondence, a larger envelope supply, and the stated privacy-protection interior pattern. Choose Yeplan 60PCS #10 Envelopes for a smaller mailing project, a lower listed price, or when its stated 24LB paper and blue security tint pattern are the deciding details. Since both are white, no-window #10 self-seal envelopes, matching the quantity to your expected mailing volume is the simplest way to decide.
