If you need a way to store a bunch of keys, the best option is to use a premium quality split ring. If you have ever used a flimsy or non-nickel plated split ring that does not bounce back into shape when you slide several keys onto it, you will know why it is a smart investment to purchase high quality nickel plated split rings. At Telkee, we only supply high end, long lasting key holders in 25mm diameter.
