Sealed Air Jiffylite Mailer Size 4 – Carton of 100 | Bubble-Cushioned Shipping Envelopes

Your medium-sized items don't fit in a small mailer, but a full box is overkill and eats your postage. The Size 4 Jiffylite hits the middle. Lightweight bubble cushioning inside, white kraft paper outside. Your product arrives intact, your parcel looks sharp, and your shipping cost stays reasonable. 100 per carton means you're not making three trips to the post office mid-week. Add to cart and get back to packing
