The flexible blue tips get a good grip on awkward or slippery surfaces without scratching. And since each clamp opens up to a generous 70mm, we never have any trouble holding chunky branches or thick tabletops. They work outdoors too - perfect for exterior cabling and displays. Sold individually at 10cm, they fit right into a resealable bag for easy storage when you're done (though honestly - we leave ours out year round).
