About
Children tend to be most pleased with obnoxious toys, and this quacking keycap toy was an instant hit with mine. Wouldn't your friend's kids love to have one? I'm sure your friend would appreciate it.
Rechargeable via USB-C with 8-hour battery life, it doubles as a keychain so the quacking can follow them everywhere. You're welcome.
