Bubble Mailers 3.5X5.9 Inch 50 Pack Small Padded Envelopes Poly Thicken Padded Self Seal Envelopes Bags(Black)

These work out great for my small business. I’ve had no complaints about damaged items. My shipping labels stick to the envelope with no trouble. The adhesive on the flap seals the envelope well and is overall a good product!

Have ordered a lot of different 4x6 mailers and these are great, large quantity, arrives quickly, actually protects what you put in them. Buy these for selling cards all the time.

Note the size carefully and make sure the small size is suitable for what you need. These envelopes work well for shipping playing/trading cards. Single cards in toploaders work well but these envelopes will also hold up to TWO 40-card homemade bulk packs, 80 cards total (see last two photos). Might be able to cram 100 loose, unsleeved singles in but it would be iffy and a very tight fit. I plan to order some slightly bigger envelopes for larger quantities cards and just use these for singles in toploaders and small quantities (under 50ish cards). This bubble mailer has better bubbles than a similar-but-thinner envelope from another seller so is thicker and offers more protection than the competition. Postal worker did warn that these envelopes do better when loaded fuller and shipped as packages vs shipped as letters. The letter processing machines can toss them around. Not sure why that is any more of an issue with these vs postcards or normal lightweight letters passing through the machines but she was being very positive & helpful so I'll definitely consider her input on that. The peel-and stick closure works well--zero worries about it coming undone. I like the peace of mind of knowing these plastic envelopes provide better moisture protection than traditional paper mailers. The black color is true black and looks very professional.

I've used few hundred thus far with not one customer complaint about a damaged or missing item. Well worth it.

My daughter uses these all the time for her online business. She loves them.

I bought these to send some thumb drives to people. When I took them to the post office to mail, I was pleased to learn they require only one standard postage stamp to mail. They are sturdy, with good stickup on the flap. Other colors would be nice, but I’m okay with pink.

Of course, there is a measurement on there, but somehow, in real life they are much smaller than expected... Going to the post office with them for the first time, the clerks were a bit baffled at what to do with these and the labels. Ended up placing the label across both sides, address etc. on one side, code on the other side. That way it worked, but it definitely makes it more fiddely. I like the quality, but won't repurchase this size again. Also I heard that black mailers can get lost more easily when they are not taped somehow on both sides (they can easily get overlooked in the box), so keep that in mind. I'm going with the old kraft syle now. Less plastic, too..

Good quality, just as advertised, held the items I needed to send and had no issues. The adhesive works well. Black is perfect for what I needed and looks professional. Thick enough to protect the items inside. Great value for the price in my opinion.

I wanted to leave a feedback for these pink envelopes as they have surpassed my expectations. The envelopes are the perfect size to ship make up (foundation, powders, eye shadow and more). They are very sturdy and once you close them you cannot open the envelope easily which is great. I’ll tell my reseller friends about this envelopes as they are useful.

These will work for what I needed. But will order the bigger ones next time. Other than that fits photos and they are nicely made. Good quality.

Perfusion for shipping pens to clients. Love the colour.

My only critique is that I wish the outside was a matte paper-like material as the plastic feels cheap.

These are the perfect size for shipping a single trading cards with a toploader. It's a snug fit, and you could probably fit a maximum of 3 regular sized 35pt toploaders.
