These envelopes are great for a durable, waterproof, adjustable-size mailing. The Tyvek is thin, but it is completely opaque. We've used them two years in a row, and we have had no issues.

Was pleased with the price and the prompt delivery of my order. These will do nicely to hold clients monthly / yearly bookkeeping documents and can be used to mail them back to the client if necessary.

These are properly sized, well made credit card sleeves that I believe will do the job I wanted them to, protecting my credit cards from abuse in my pockets and wallet. I'd buy them again if I ran out. I write on them easily with Sharpie markers; I'd guess any similar permanent marker would do the job.

I love these card protectors! My bank no longer carries them and for the price and the amount you get here you can't beat it. I use these alot for my cards and also when going places and I don't want to carry my purse I just put my cards and ID all in one and bam everything in one pocket. Easy to write on if needed and the material is great because it won't rip easy at all like regualar paper ones. Glad I found these!
