Columbian #10 Security Envelopes, 500Box, No Window, 4-18 x 9-12 Inches, Release & Seal Self Seal, White COLO151

The Columbian #10 Security Envelopes have received mixed reviews from customers. Some users have found them to be perfectly functional and a good replacement for labels in their office. They appreciate the quality of the product for the price and find the security feature effective. However, there are a number of complaints about the quality of the envelopes. Some customers have noticed that the color of the envelopes is blotchy and semi-visible from the outside, as they are too sheer. The envelopes are also described as off-white and not entirely opaque. The lower crease on the envelope makes it difficult to stuff them, and they are not cut as shown in the product photos. Customers have also mentioned that markers bleed through the envelopes, which can stain the contents inside. Some users have expressed disappointment in the overall quality and appearance of the envelopes, mentioning that they look cheap and unprofessional. It seems that the quality of the Columbian #10 Security Envelopes has declined over the years, as older versions were praised for being 100% opaque, brighter white, and of better overall quality.
