We can not insert items thicker than 1/8". We do not hand insert bulky items such as pens, USB sticks, or any items that are not flexible. Your cost will vary based on the size and the type of item being inserted into each mailer. Having multiple items inserted into a single mailer will also increase your cost. The cost is based on the size of the promotional item being inserted. Choose a level of service where your promotional item fits. There is no matching, which means that the promotional item can not be uniquely addressed to each mailer.
Hand inserting may add one or several additional days to your production time depending upon the number of items that need to be inserted. Please inquire about the additional time needed if your order is +2500 pieces.
USPS will apply additional fees if your piece does not pass the flexibility test explained below. For a full explanation of the physical standards of your mail piece, please refer to this USPS document.
