The process
From your pet's photo to a working NFC tag, delivered to your door.
01 —
Upload a clear portrait — face and chest preferred. We use it to generate the illustration in your chosen art style.
02 —
Five art styles, three background tiers. We generate a proof image before printing — you approve it first.
03 —
3D-printed in PETG, UV-printed with your illustration, NFC-programmed with your pet's full profile. Dispatched in 3–5 working days.
04 —
No app needed. Any iPhone or Android phone taps the tag and instantly shows your pet's contacts, medical info, and address.
Customisation
Each illustration is generated from your pet's photo and UV-printed on the tag. Every tag is unique.
Bold carved marks, high contrast. The most graphic style — reads perfectly at every tag size.
Soft, wet-on-wet washes on cream paper. Clean, delicate, and warm. Best for portraits with fine fur detail.
Triangular facets at maximum vibrancy. The most contemporary style — bold and striking.

Our story
"Willo is the name they share — Willow, who came first, and Loki, who came loudest."
Willo started as a practical problem: a lost pet, a plain tag, and a phone number that went unanswered. Every tag we make is designed to work the moment it's needed — tap any phone, see everything.
Each tag is 3D-printed in PETG, UV-printed with a unique illustration generated from your pet's own photo, and programmed with your pet's full profile. You choose the art style; we make the rest.
Made in Singapore, one at a time, by someone who knows what it means to love an animal too much.
Loki & Willow
The dogs behind the brand
Willo is a small Singapore brand run by Felice Yee — a marketer turned maker with a Bambu Lab printer, a UV press, and two dogs who inspired everything.
Questions
Hold any iPhone or Android phone near the tag — the phone detects the NFC chip and opens your pet's profile in the browser automatically. No app needed. Works even without mobile data.
Owner contact, backup contact, vet clinic, 24hr emergency number, allergy alert, medications, microchip number, home address, and notes for the finder. You can update any of these yourself anytime using your PIN.
Yes. Every tag comes with a PIN. Tap the tag → scroll to "Update my details" → enter your PIN → edit anything. Changes save immediately and the tag link never changes.
30mm for cats and toy breeds under 5kg. 35mm for small-to-medium dogs (Corgis, French Bulldogs, Beagles) — our most popular size. 45mm for larger dogs. If in doubt, go 35mm.
The PETG body is water-resistant. The NFC chip and illustration are sealed beneath a UV coat. Designed for rain, swimming, and outdoor use. Prolonged saltwater submersion is not recommended.
Proof image sent within 1–2 working days. After approval, printed and dispatched within 3 working days. Total: 5–7 working days to your door.
Yes. The 30mm tag is designed with cats in mind — lightweight, using a 22mm NFC chip. The Linocut and Geometric styles work especially well at this size.
A clear photo of your pet's face looking toward the camera, head-and-chest framing. Good lighting matters more than resolution. We'll let you know if the photo isn't suitable before generating.
Update it yourself using the PIN on your pet's profile page. The NFC tag link stays the same regardless of how many times you update the information behind it.
Currently Singapore only. If you're outside Singapore and interested, drop us a message — we're exploring international shipping.
