These anal beads are great beginner beads. They have visible seams, but they aren’t sharp and aren’t noticed while in use. Plus, these are SUPER easy to clean.I got these for my girlfriend who wanted to explore. She was scared to try at first but loves them and insisted that I order more (that are slightly larger). These are a decent size set for beginners. Don’t have to worry about them getting stuck inside with the loop at the end.
