This magnet measures approximately 3.5"x1.6" with a strong 1" ceramic magnet on the back. Made from 3/16" thick maple veneered wood in our solar powered Santa Cruz, California workshop. Every product we create is made from 100% sustainably harvested, American grown wood. Our magnets are very strong and will have no problem securing your favorite photos to the fridge :) This product is great for stores that feature whale watching, marinas, marine mammal, ocean sanctuary, boat tours, Monterey Bay, San Diego, Port Townsend, San Juans, Vancouver Island, Santa Barbara, Dana Point, Alaska, sea life, and marine tourism. We also offer this design as an ornament and keychain! This design was drawn by me. It's not clipart so you'll only find it in our store :) Please note - every wood item is unique and colors and grain can vary from piece to piece.
