Quality Park Sealed Air Jiffy Lite Cushioned Mailers, Self Seal, 5, 10.5 x 16 Inches, Pack of 25 (SEL10190), Brown Kraft

For the price they do as advertised.

Have been using these for years, just not a lot of them. They are too big for my items so in some cases I have to use a different size. Go figure.

I used a LOT of Size 5 (10.5 16) Mailers all the time for my eBay auctions. These are so far the most disappointing. These envelopes are very narrow and were unable to fit my items that would usually fit in a Size 5. With certain brands such as Office Depot, the item fits perfectly. Other brands that I have found on Amazon such as Ecolite will require me to modify the envelope a little bit to make the item fit. These mailers, however, do not fit at all. It seems that the dimensions stated are the external dimensions of the mailer rather than the internal so you do not get as much space as you would with another #5 mailer. Quality-wise, these mailers aren't the worst I've encountered. The quality of the paper and bubble padding is pretty good quality and I wouldn't expect tears or punctures from it. If you need a couple Size 5 envelopes but aren't worried about the size of your items, these are OK. However, if space is really an issue for you and you need 10.5 x 16 INTERNAL dimensions, these will not serve your purpose. Returned for a refund.

Everything we've ordered is exactly what we needed. Easy to find online and product was shipped within a couple days.

Good envelop.
