Excellent price for the amount you get, and the sealing strip works well. I'll be buying more when I run out for sure.

I run an eBay store selling sports cards, and these black A4 envelopes have been a total game-changer for my shipping presentation. I use them for the "eBay Standard Envelope" service, and they provide a much more professional, premium feel than a standard white envelope. The 4x6 size is perfect—it’s just the right amount of space to hold a card in a penny sleeve and top loader, plus a packing slip, without being so large that the contents slide around. The self-seal strip is a huge time-saver when I'm packing dozens of orders at once; it's very secure and I haven't had a single issue with one popping open in transit. Despite being a sleek black, they are still flexible enough to pass through the USPS sorting machines without a problem, keeping my shipping costs low while making my brand look high-end. If you’re a card seller looking to level up your packaging and give your customers a better unboxing experience, these are definitely the way to go. I’ll be keeping these in stock for my shop from now on!

This is my bi-monthly supply for my crafting hobby. The quality and price are the two keys fir the selection.

Beautiful color with full saturation across the entire envelope. Nice middle-weight – not too flimsy or too thick. Great pull tab for closure. The size was true without being too tight or too big. And I was able to put three pieces of card stock inside easily. I used metallic paint pens for addressing and the ink and the paper combined well without issue. I would buy these envelopes again in this color if needed or I may try a different color next time. Highly recommend.

If you're like me and always mess up envelops when writing cards, it's a good idea to have these extras nearby..."Just In Case". These a perfect for my needs!
