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. Review: Value, quality and quick shipping. All important to me - Fast ship, just the size I needed and quality bags!! Plus the pink is perfect. Good thickness for shipping out clothing items. Great price too!! Will be back for more. ## 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 | #1,507 in Office Products ( See Top 100 in Office Products ) #2 in Bulk Envelope Mailers #23 in Envelope Mailers | | Brand Name | UCGOU | | Closure Type | Self-Seal | | Color | White | | Customer Reviews | 4.8 4.8 out of 5 stars (20,775) | | Item Dimensions L x W | 24"L x 19"W | | Item Shape | Rectangular | | 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 ![UCGOU 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) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sturdy Poly Mailer Bags *by K***S on November 27, 2025* Great mailer bags and quality.
