Japan Key Protectors
I picked up a Rilakkuma key protector for my apartment keys. It came in a round plastic ball which when opened popped out the “HAPPY XMAS” Rilakkuma themed protector. The idea is that it covers the top of the key so that you have a softer object in your bag or pocket when carrying around your keys.
You can see on my key chain I also have a small Tokyo Station plate and DoCoMo character goods.
The key for my apartment has dimples in it rather than just a cut line. This is supposed to make it harder to forge the keys. It also looks a lot cooler ^^.
What are keys like in your part of the world? Do they have dimple ones like this? Do you have key protectors as well?
