How it works
1. Choose a gift or send your idea.
Pick a product, or email us what you have in mind.
2. Get a free design proof.
We make the design. You check it and ask for changes if you want.
3. We engrave it.
After you approve, we engrave it with our laser. Engraving is permanent. It does not wash or peel off.
4. We ship it.
Small orders (1–10 pieces) can often ship the same day if you approve the proof early. Larger orders usually ship 3–5 business days after approval. Express orders usually get priority.
Have an idea? We love custom projects.
Not sure what you need? We are happy to help with design and ideas. Send us your words, a sketch, or your logo. Any file format works. A clear, high-quality file gives the best result. One-of-a-kind and unusual requests are welcome.
