What's in the box

Which grade is right for you?
All of our devices are 100% fully functional. Our grading relates to the physical condition of devices.
We work hard to source the best used Apple devices, refurbish them to the highest standards and reintroduce them back into circulation. This extends each product’s life, puts those raw materials back to use and greatly reduces e-waste generated from over consumption.
