Just what the doctor ordered. No licking and as such just might stop the spread of the Wuhan global pandemic. It's as good of an idea as everything else I've heard. I would recommend these envelopes to everyone.
I do not have a problem with the performance of the envelope but do have a complaint about the available selections. I really wanted the plain gummed envelopes 100 pack which I believe are less expensive and more environmentally friendly. Those envelopes were only available in my store in a 500 pack. I opted for the easy close 100 pack and the clerk gave me a discount to compensate for the extra cost so I think they did all they could.
