Review: Peace of mind when shipping USPS - This is a really useful tool to have on hand for anyone who mails out a lot of USPS mail. I ship a lot of greetings cards, and was getting anxious as to whether I'd correctly measured the thickness of the cards and paid the correct amount of postage. Now this is a worry of the past - If I have any concerns about the thickness or size of an envelope, I just use this handy little tool and know straight away. The measurements printed on the plastic are very clear, and the overall quality seems excellent. I wish it had been a different color, as it is clear and easily misplaced. Although I'm happy with my product, I only gave it 4 stars because I felt that $19.99 was a bit overpriced for what is basically a piece of plastic with some slits cut into it.
Review: Works for USPS mail - I like that the slots are labeled. I use this for pen pal mail. It's funny that a Canadian company thought to produce this. However, it is the best instrument I have found on the market. A little pricey but it serves a specific purpose. Also, be careful with it as this kind of plastic is not reinforced and while it is thick, if you drop it, it might crack, so just be careful.
