Please look what I bought at the craft store in my area. Spike beads in 12x18mm. In the large size, I didn't know the spikes. I took in crystal copper AB and jet hematite. There also were some other colors.
For me the selection was very difficult and so I've turned the boxes 10 minutes in my hands back and forth, until I could finally decide me. ;-)
