Sobres de burbujas n.° 0 de 6 x 10 pulgadas | Tamaño útil: 6 x 9 pulgadas

Most Size #0 bubble mailers are listed as 6" x 10" outside, which is 15.2 x 25.4 cm. Usable inside space varies by brand, but common specs are:

• About 6" x 9" usable = 15.2 x 22.9 cm
• Some list about 5 7/8" x 8 3/4" usable = 14.9 x 22.2 cm

There’s no reliable “stamp count” because USPS will usually treat a bubble mailer as a package and charge based on weight, thickness, and destination. Practically, you either buy/print a package label or take it to the counter and they’ll tell you the exact postage.

Empty weight varies a lot by material and thickness. Many poly 6x9 mailers are roughly about 0.2 to 0.5 oz each.

Good for small, low-profile items such as:

• Jewelry, small accessories, key fobs
• Phone cases, small cables/adapters, small electronics parts
• Trading cards/collectibles (protected)
• Small cosmetics (lipstick, samples)
• Thin apparel like socks or underwear (if not bulky)

Usually no. USPS “letter” pricing requires a piece to be flat and no more than 1/4" thick, and bubble mailers are often padded/rigid enough to be handled as a package.
