A scruffy little troll perched at the bottom of your strings — the kind that lives under bridges in old fairy tales, now living between the mains of your racquet.

Silicone construction. Slides in between the two bottom main strings and dampens the high-pitched ping the strings make at contact. 2-pack — dampeners are notoriously easy to lose at the courts, so a spare is welcome.

Good fit for:

• The teammate with a self-deprecating sense of humor
• A junior who loved fairy tales as a kid and now plays competitive tennis
• A small add-on to a birthday card for someone who appreciates the odd and ugly
