The hole is tight enough that my knot stays put but still threads easily with a big-eye needle. I love that these are 100% silicone so they're safe for teething projects, and the 15mm size gives a nice substantial feel without being bulky.

The 15mm beads are nicely chunky with a smooth finish, and the 1-2mm hole works perfectly for my thicker cord. Colors arrived true to the photos, and I appreciated that they're sold individually so I could grab exactly the shades I needed.

I was a little worried about the size but these 15mm beads are perfect for my chunky bracelet projects. The silicone is soft and flexible, and even with the tiny hole, they thread onto my thicker cord without any trouble.
