Extra Large Bubble Mailers 31.5 x 23.6 in - 10 Pack Resealable Padded

In this review the Thenshop extra large bubble mailers are judged on protection, size and convenience for shipping bulky soft goods. They are best for small businesses or home sellers who need oversized, waterproof cushioned envelopes that arrive ready to seal. The single biggest reason to buy is the combination of a true large internal size and dense bubble padding, which together keep jackets, posters or multiple garments protected without additional wrapping.

Key Features

• Extra large dimensions: Each envelope measures approx. 31.5 x 23.6 in so it accommodates large garments, posters or folded textiles without tight creases.
• Pack of ten: The 10-piece package supplies enough mailers for repetitive shipping runs or a small shop without frequent reordering.
• Waterproof PE shell: The polyethylene outer makes the mailers dirt proof and resistant to light moisture during transit.
• Dense bubble padding: Sufficient internal bubbles provide cushioning to reduce impact damage to soft or flat items in mailing.
• Self-adhesive closure: The peel-and-seal strip enables quick resealable packing and secure closure without tape or tools.
• Lightweight construction: Being lightweight helps keep postage costs down compared with heavier rigid boxes.

Who It's For

These large bubble mailers suit independent sellers, clothing resellers and small boutiques who ship apparel such as jackets, scarves and pants or large-format flat items like posters and documents. The capacity and cushioning are tailored to shipments that need protection without bulkier boxes.

Those who should look elsewhere include sellers of fragile breakable goods that require rigid protection or anyone needing custom-sized or padded boxes for heavy items; these poly mailers are not rigid and are best for soft, flat or flexible contents.

Pros & Cons

Pros

• True extra large size fits bulky clothing and wide-format items with room for the item plus padding.
• Waterproof PE material keeps contents protected from damp and dirt in transit.
• Dense internal bubbles provide reliable cushioning without adding much weight.
• Self-adhesive design speeds packing and ensures a secure seal for each shipment.

Cons

• Not suitable for fragile rigid items that need box-style protection and structural support.
• The white opaque surface may show scuffs if rough handled, though it remains functional.

Frequently Asked Questions

Are these mailers waterproof?
Yes, the PE outer material is waterproof and helps protect contents from light moisture and dirt during transit.

What size items will fit?
Items smaller than the internal 31.5 x 23.6 in footprint and that are not rigid should fit well; allow for item thickness when planning fit and sealing.

Do they require tape to seal?
No, the envelopes have a self-adhesive peel-and-seal closure so tape is not necessary for a secure seal.
