An original puzzle designed by Frank Potts, made and given in IPP42 exchange in Tokyo, 2025. I’ve added a printed solution sheet but could also give you the BurrTools file if you need it.
Goal: Remove the 3 stamped envelopes from the LetterBox and put them back in again. You’ve got plenty of time; it’s snail mail.

The puzzle is laser cut from 3mm clear acrylic and 5mm white and blue acrylic pieces.
Size: Base: 65mm x 65mm x 10mm Clear box: 48mm x 48mm x 48mm.
Packaged in a kraft cardboard box.

The import duty or tariff rate may be different for every country so please check the rate that applies to your own country.
It is usual practice that import duties or tariffs are paid by the buyer at the point of import or delivery in your own country.
USA is the exception. The USA government has mandated that the tariff be paid to them from Australia before we can send the parcel. The tariff percentage may be different depending on where the puzzle was made. For Mr Puzzle puzzles made here in Australia the rate is 10% + Admin fee.
