Selling due to decluttering for a move. These are envelopes for resumes. There are 10 envelopes in the pack, and it has never been opened. The packaging method is as follows: waterproof protection over this vinyl, reinforced cardboard, and then an envelope. They have been stored in a dark place. I plan to put them up for sale for about a week, and if they don't sell, I will take them to a recycling shop or another website. Immediate purchase and silent transaction are OK. Please use them in your daily life.
