The case itself is is really easy to fit onto your phone, and includes instructions for you to do this.
1. Grab your rubber bumper, coloured insert and clear backplate
2. Take the rubber bumper and pop it around the edge of your phone, ensuring all the buttons are lined up
3. Place your chosen insert onto the back of your phone
4. Click the plastic backplate to the rubber bumper
That's it! It's pretty foolproof and very easy to do as long as you follow the steps in that order.
The only critique I have about the design is that the bumper is so thick it can be difficult to reach the silent switch without really having to poke your nail in there, but it's a compromise I'm willing to make for the protection the bumper gives.
Here are my finished inserts for each set. I used markers on them all and there was no bleed or anything onto the other side- not that it matters! Overall I'd certainly recommend these cases for the avid colourist and JB fan, or just as a gift for someone who likes pretty accessories. You could even colour them all yourself before giving as a personalised present :)
iPad Air 2 & Mini cases are also available.
