Query: Pretty good, just inconsistent quality from all the various sellers

I have ordered these envelopes many times from various sellers on here just because the one I normally order from may be out, or I just hit the Add to Cart button without looking. They obviously all do what they are intended to do, but I have found I like some better than others. The ones I like the best don't have a weird odor, and take a little bit for the adhesive to set in. Unfortunately I do not recall which seller had the best one and my entire review is basically just going to tell you to buy it from one seller and if you like it, remember which seller it was because they are all selling the same sized but different made envelopes.
