  • To send your Slotbox in when mailing

    The end opening style “catalogue envelope”is preferred. Do not use a bubble mailer.

    Small Box Envelope - 5 7/8” x 9 5/8" or 6” x 9”

    Small Plus Box Envelope - 5 7/8” x 9 5/8” or 6” x 9”

    Medium Box Envelope - 5 7/8” x 9 5/8” is a snug fit on the width but fine for length. A better option for a little more room is 6” × 9” or a 6.5” x 9.5”.

    Large Box Envelope - 9” x 12” or 10” x 13” are both great choices.

    XL Box Envelope - 10” x 13” is a squeeze for sure but can work, best to go a little larger.

  • To weigh your mail for accurate postage

    When it comes to buying a scale, you do not need a fancy expensive one. A standard kitchen scale meant for lighter items will do the trick.

    Canadian Tire, The Bay, or any kitchen store will have scales. Of course, you can find them on-line too.

  • A great brand starts with a great logo

    Design your own on a platform or hire a local graphic designer to do it for you.
