Duck Self-Seal Kraft Bubble Mailer #5 vs XYRSRUW Bubble Mailers 10x14

Both are self-seal kraft bubble mailers with similar padding, so the real difference is size and track record. The Duck #5 is the larger of the two at 10.5" x 15" and carries a 4.7 rating across more than 2,000 reviews, which is the safer bet if you ship books, crafts or anything bulky. The XYRSRUW is slightly smaller at 10 x 14 and is a lesser-known brand with little owner feedback, so pick it only if that size fits your items better. Neither is heavy-duty; both suit light to medium shipping.

• Choose the Duck Self-Seal Kraft Bubble Mailer if you want the larger 10.5" x 15" size and a brand with thousands of owner ratings behind it.
• Choose the XYRSRUW Bubble Mailers if your items fit a 10 x 14 envelope and you want a recyclable-material option.
