    I make handmade jewelry and these boxes allow me to ship lettermail all over Canada and US! I saw some reviews saying the boxes were difficult to close but I haven’t had any issues so far. Great boxes ABSOLUTELY recommend for small businesse owners.

    It's the exact size I needed for small items and postcards to ship letter size mail ? It was cheap, and was ready to pick up very quickly.

    Lettermail Boxes

    Hello Zakka! Your letter mail / slot boxes are just what our company needed!! They provide excellent protection for small fragile items and we've had no trouble shipping them with letter sized mail. The closing tabs are a little tough to work with as they seems to split open a bit easily on the ends when sealing the final product, but otherwise, very pleased to have found this product!! Thx! ~ Alysha shipping / receiving / ordering Paramount Coastal Designs Ltd.

    such a great product for mailing products within Canada. I recommend this to other businesses all the time. I get the odd one that is misshaped or damaged, and I usually cut off the little tabs on the lid. works great!
