Review: Nice looking and a great value. - My second time purchasing the Ucgou poly mailers. A great value for the price. While not the thickest poly mailers I've used, they're also far from being the thinnest and a good sturdy mid-weight. Thus far, no issues with tearing. The self-adhesive strip at the top seals well. Our customers love the color (teal) and they're a size that lends itself to many uses. All in all, a great value. Review: Sturdy Poly Mailer Bags - Great mailer bags and quality. My 2nd time purchasing these, but this time in black because they were on sale for a reasonable price and had prime shipping, I was disappointed the blue ones were not; didn't make sense. Thickness is pretty good, they're not see through so couldn't see what you're shipping. Adhesive seal is good, but I always go back and tape over seal for extra caution. These are easy to use, flexible, and functional. Love the size of these as well. ## Features - Premium Quality: Large poly mailers constructed with durable, waterproof material ensuring maximum protection for your items during transit - Self-Sealing Design: Strong adhesive strip provides secure closure without requiring additional tape, making packaging quick and efficient - Tear-Proof Material: Reinforced construction prevents rips and tears, maintaining package integrity from origin to destination - Versatile Usage: Perfect for shipping clothing, soft goods, accessories, and other non-fragile items with professional presentation - Weather Resistant: Waterproof exterior shields contents from moisture and environmental elements, keeping items safe and dry ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08YRMN674 | | Additional Features | Waterproof | | Best Sellers Rank | #1,304 in Office Products ( See Top 100 in Office Products ) #4 in Bulk Envelope Mailers #21 in Envelope Mailers | | Brand | UCGOU | | Brand Name | UCGOU | | Closure Type | Self-Seal | | Color | White | | Customer Reviews | 4.8 out of 5 stars 20,801 Reviews | | Item Dimensions L x W | 24"L x 19"W | | Item Shape | Rectangular | | Material | Plastic | | Material Type | Plastic | | Number of Items | 100 | | Occasion | everyday mailing | | Size | 19x24" 100PC | | Style | Poly | | Unit Count | 100 Count | ## Product Details - **Brand:** UCGOU - **Closure Type:** Self-Seal - **Color:** White - **Material:** Plastic - **Occasion:** everyday mailing ## Images ![Poly Mailers 19x24 Inch White 100 Pack Extra Large Shipping Bags Strong Thick Mailing Envelopes Self Seal Adhesive Waterproof and Tear Proof Boutique Postal for Clothing Quilt and More - Image 1](https://m.media-amazon.com/images/I/61cM-rb3J2L.jpg) ![Poly Mailers 19x24 Inch White 100 Pack Extra Large Shipping Bags Strong Thick Mailing Envelopes Self Seal Adhesive Waterproof and Tear Proof Boutique Postal for Clothing Quilt and More - Image 2](https://m.media-amazon.com/images/I/61l0Q6yIgFS.jpg) ![Poly Mailers 19x24 Inch White 100 Pack Extra Large Shipping Bags Strong Thick Mailing Envelopes Self Seal Adhesive Waterproof and Tear Proof Boutique Postal for Clothing Quilt and More - Image 3](https://m.media-amazon.com/images/I/71M2RBM+6+L.jpg) ![Poly Mailers 19x24 Inch White 100 Pack Extra Large Shipping Bags Strong Thick Mailing Envelopes Self Seal Adhesive Waterproof and Tear Proof Boutique Postal for Clothing Quilt and More - Image 4](https://m.media-amazon.com/images/I/61OLW9vjn2L.jpg) ![Poly Mailers 19x24 Inch White 100 Pack Extra Large Shipping Bags Strong Thick Mailing Envelopes Self Seal Adhesive Waterproof and Tear Proof Boutique Postal for Clothing Quilt and More - Image 5](https://m.media-amazon.com/images/I/61NB9sSJ7FS.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice looking and a great value. *by B***L on April 19, 2026* My second time purchasing the Ucgou poly mailers.
