Good to know

Everything you need to know about ONKO's patent pending button jewellery

Make sure you have compatible buttons in your shirt
Ideal shirt buttons for our jewellery are between 10 - 13 mm in width and around 2,5 mm in thickness. We know that telling you about measurements might be overwhelming – but if your shirt has really basic buttons they are probably standard sized, which is 11 mm.

You can also see a video here about different shirts and their buttons.

 

How to wear your button jewellery?
Our button jewellery is meant for shirts that are buttoned up. This ensures that the jewellery fit is tight enough and does not fall off.

Practice first:
For your first use, try attaching the jewellery to a button that’s easy to reach—like one in the middle section of your clothing—before working with tighter buttons, such as a top collar button. This helps you get a feel for the attachment process.

Slide the jewellery onto the button:
Gently slide the button into the groove of the jewellery. The lip will secure the button in place, ensuring a firm and secure fit.

Check for a good fit:
Once attached, the jewellery should sit comfortably on the button without sliding. The recessed design will protect the button’s threads during use.

Remove with ease:
To remove, tilt the jewellery slightly and slide the button out of the groove.

In case you find yourself stuck:
If the jewellery feels stuck, you can lift the button manually using a fitting object, such as a pen, key, or similar tool. For better visibility, try turning the jewellery upside down and carefully work the button out.

Derived from the Finnish language, 'ONKO' embodies the spirit of curiosity and questioning. It represents a brand that celebrates the thrill of trying out new things and embracing the unknown. Our brand is a sanctuary for those who dare to try new things, unfettered by the fear of failure.

At ONKO Jewellery, we celebrate the art of exploring, whether it's in design, materials, or creative expressions. Each piece is thoughtfully designed to be timeless and versatile, effortlessly transitioning from day to night – and effortlessly complementing any outfit or occasion.

Join us on this extraordinary journey and let our jewellery be an extension of your true self.

Jewellery
All of our jewellery is made from recycled sterling silver. Our silver comes from K.A. Rasmussen oy, Finland.

Boxes
Our boxes are ECO products from Westpack (Denmark). Boxes are made in a factory in Denmark using FSC®-certified cardboard and water-based glue.

Process
Our product design usually begins with hand-drawn sketches, followed by physical prototyping and refinement through precise 3D modeling. Once perfected, the final 3D model is sent to Koruvalimo K. Raiskinen Oy in Kirkkonummi, Finland, for casting. After casting, each piece is carefully hand-finished in our studio and thoroughly tested to ensure quality.

Any excess silver from the production process is melted down and reused, minimizing waste and supporting environmentally responsible craftsmanship.

Our future plans
In addition to using recycled sterling silver and FSC®-certified packaging, we are actively working to ensure that more of our materials, such as packaging boxes, will be sourced locally in Finland in the future. This will further support our goal of minimizing our carbon footprint and strengthening local partnerships.

We are eager to take part in testing and innovating new sustainable solutions within the jewellery industry! If you are looking for partners for testing out new solutions or cooking some new ideas don't hesitate to contact us at onkojewellery@gmail.com. Let's do it!

Keep your goodies in good shape

→ Wear with Care:
Sterling silver can scratch or tarnish over time.

Avoid exposing your jewellery to harsh chemicals such as perfumes, lotions, or cleaning products, which can dull the finish.

→ Cleaning your jewellery:
Gently clean your silver pieces using a soft polishing cloth to restore their shine. For more thorough cleaning, use a mild soap and lukewarm water solution. Rinse well and dry with a soft, lint-free cloth. Avoid abrasive materials that can scratch the silver.

→ Storing your jewellery:
When not in use, store your jewellery in a cool, dry place, ideally in a fabric-lined box or a soft pouch to prevent tarnishing and scratches. Storing pieces separately ensures they don’t rub against each other.

→ Regular maintenance:
Exposure to air and moisture can cause silver to tarnish. If your jewellery becomes heavily tarnished, use a silver-specific cleaner to restore its shine. Be sure to follow the product’s instructions carefully, and use a soft cloth for application.

By following these care instructions, your ONKO jewellery will continue to shine and be a lasting part of your style for years to come.
