1. X-Large Extra Wide-Long Fit for All Spacious Item Needs

50/100 Pcs of 10.6x14.2 Inch X-Large extra wide-long fit bubble mailers, designed to accommodate a variety of spacious wide-long items—such as long mid-thigh coats, 16-inch laptops with thick protective cases and full peripherals, large fabric storage bags for quilts or blankets, thick long pet beds (for medium to large pets), and oversized folded winter sweater + pants sets. The 50 Pcs pack is perfect for personal use (e.g., sending birthday gifts, packing travel essentials), while the 100 Pcs bulk option meets family storage needs, studio shipping demands, and daily mailing requirements, with flexible quantities to avoid overstocking.

2. Heavy-Duty Protection for Fragile Items

Crafted from 2.6mm thick tear-resistant polyethylene, paired with dense 3.2mm bubble layers, these padded mailers provide strong shock absorption to protect fragile contents. They effectively shield 16-inch laptop screens from scratches, fabric storage bag seams from splitting, pet bed padding from clumping, and winter clothing wool trims from shedding—keeping items safe from bumps, dust, and minor impacts during transit. Suitable for local deliveries, cross-border shipping, and long-haul transportation alike.

3. Hassle-Free Self-Sealing for Efficient Packaging

Equipped with a 1.6-inch wide high-adhesion self-sealing strip, precisely cut to match the mailer’s size—no extra tape or glue is needed. Simply peel off the protective liner and press firmly to seal securely, even for slightly bulky items (e.g., a 16-inch laptop + charger + keyboard + mouse, or a long coat + gift box). The lightweight design (most 50 Pcs packs weigh under 2lb) helps reduce shipping costs, whether you’re mailing personal items, organizing home supplies, or sending out small orders.

4. 100% Waterproof for All-Weather Shipping

The water-resistant outer layer repels rain, snow, and accidental spills, ensuring contents stay dry and intact. It works perfectly for fabric items (coats, pet beds, storage bags) that fear water stains, as well as electronic devices (laptops, peripherals) that need moisture protection—eliminating the need for additional plastic wrap or waterproof bags. Ideal for outdoor drop-offs, rainy-day mailing, and unpredictable weather conditions.

5. Cost-Effective & Versatile for Daily Use

Made from high-quality reusable materials, these mailers are durable and resistant to minor wear and tear, suitable for eco-conscious users looking to reduce waste. Sealed edges won’t split even when holding items up to 5.8lb, supporting repeated use. Compared to single-piece purchases or mismatched small/mid-size mailers, the 100 Pcs bulk pack saves an average of 34% in costs. Its versatile size also eliminates the need to stock multiple packaging types, simplifying mailing and storage for all scenarios.
