This is an armor aluminum alloy case designed for the Raspberry Pi 4 computer model b. It is a great passive cooling case to help raspberry pi 4 board cooling down.
Note: the raspberry pi 4 board is not inlcuded in the packing list.

The Raspberry Pi Pico is an entirely new type of microcontroller from Raspberry Pi. Small, cheap and flexible - it’s great for learning to code with MicroPython!
The Pico isn’t designed to replace the Raspberry Pi, which is a different class of device known as a single-board computer.
Whereas you might use your Raspberry Pi to play games, write stories and browse the web, your Raspberry Pi Pico is designed for physical computing projects where it can control familiar components such as LEDs, buttons, sensors, motors and even other microcontrollers.
The Pico can be quickly and easily programmed using MicroPython and C/C++ using popular editors such as Thonny. Getting started is also very easy thanks to the dedicated Getting Started page.
You can program your Pico from your computer, a Raspberry Pi 4 or even another Raspberry Pi Pico!
The main chip on board is the 'RP2040' made by Raspberry Pi (their first in-house microcontroller chip!) and is a dual-core ARM Cortex M0+ processor, with a flexible clock running up to 133MHz.
