These poly mailers measure 7.5" x 10.5" and are made from polyethylene (PE). They come in white and feature excellent water and tear resistance, along with a strong self-sealing adhesive strip for quick and secure closure. Note that the usable interior space is slightly smaller than the stated dimensions due to side seams and does not include the flap area.

7.5x10.5 is one of JiaroPack's smallest poly mailer sizes, making it perfect for compact, lightweight goods. It works great for kids' clothing, thin folded tees, small accessories, jewelry pouches, light scarves, handmade craft items, and small boutique orders. For lightweight products like a single t-shirt or a folded scarf, this size handles the job well, keeping costs low without sacrificing basic protection.

These envelopes are durable and water-resistant, making them ideal for shipping items, with strong adhesive strips for a secure seal.
