Though Tyson doesn't, usually, give gifts during Christmas or other such holidays (full headcanon here) he does give gifts at other times of year, usually as thanks.
When giving gifts Tyson gives metal boxes in the shape of Rhombic Icosahedrons. As a general rule the boxes are one inch in height and are made of stainless steel with a brass coating. The Rhombic Icosahedron isn't Tyson's favourite shape, time (and mathematics) has proven that to be the regular Hexagon, but from a mathematical point of view it is still an interesting shape.
Each 'set' of gift boxes are personalised to the person he is giving it to, usually by removing part of the layer of brass to allow the stainless steel to show through to make a pattern but occasionally pieces of other metals (usually bronze or aluminium) are added. The inside of the metal boxs are always lined with felt, to keep the contense safe, the colour of which is personalised for the person he intends to give it to. For example, when giving a gift to his brother, Jethro Andrew Delaney, Tyson makes a checkerboard pattern on the container with a red lining inside & when giving a gift to Jasmine, the maid at the family manor who served as his surrogate mother, he makes a series of butterflies with a white lining inside.
There are two different ways that Tyson gives gifts through theses containers: small items and microchips.
- The small items that normally go into the boxes are usually money, jewellery, or (carefully folded, sometimes origami) letters. Tyson is very loose with his money. He grew up in a rich household with no reason to carefully monitor his expenses which leads to him often over-tipping and not checking receipts. It is rare that Tyson will buy jewellery, he doesn't really care for it, so if he does by some for a person it means that he really cares for them. Letters are important to Tyson, he thinks they are special. (Original head canon here). Every now and again there will be a small key inside the container that opens a pervious present, usually one delivered in the style bellow.
- For items too large to put into the small container Tyson uses microchips to give directions to the item or to send a digital item such as photos/programming/videos. How to use the information depends on the type of chip in the container: sometimes it will go into a GPS to give directions, sometimes it will be photo directions (usually showing the street name that a turn needs to be made at, sometimes with Tyson in the photo), sometimes it will be a digital copy of a customised map Tyson has made, and sometimes it will be step-by-step instructions on a .PDF file. Sometimes Tyson won't put directions on the microchip, sometimes it will be blank and he will put a small piece of paper (fortune-cookie fortune sized) with a riddle instead to give hints to the present or to the next clue/riddle/code.
