Merriway BH01838 (10 Pcs) White Key Ring Tags with 25mm (1 inch) Sprung Metal Split Ring - Pack of 10 Pieces

These are just what I needed. They are long enough to be able to label them indicating what they are for my spare keys box. I'm not sure that they would last that long in my pocket but for this project, they are perfect.

Smaller than thought

Super way to save fumbling through loads of keys.

It’s a key ring

I wanted these to label some items to make it easier to find what I wanted. They do the job well and are well made and good value

These are very simple but neat and won't take up too much space. Easy to write on. Not sure that the would be sufficiently robust for daily use, but ideal to keep spare keys tidy which is what I bought them for.

The tags themselves are fine, until you want to write on them (with a Sharpie marker) as the pen comes off within days

Strong enough but permanent marker wears off
