Description
The Sea Lion Metal Warning Metal Sign brings a laid-back coastal vibe to any space, featuring a sea lion sign that's built to stand out. Made from heavy gauge aluminum and printed directly onto the metal (never a flimsy decal), it's finished with a UV-protective coating. Fun fact: sea lions are loud, social, and famously unbothered by an audience, which makes them the least subtle guard animal on this list.
It's a great gift for sea lion lovers, hobbyists, and collectors alike, and makes a fun, low-effort housewarming or holiday present. Every sign is made to order and custom-imprinted in the USA, right in our Henniker, New Hampshire studio.
Does this sign come with mounting holes? Yes – every size now ships with or without pre-drilled mounting holes on the shorter ends, your choice at checkout.
Is this sign safe to hang outdoors? Yes, it's rustproof, UV-protected aluminum built to handle sun, rain, and snow for years.
