Buttons that come off, and go back on.
Every ISVARENO button has a small shank on the back. It goes through the buttonhole and a ring holds it on the inside. Change a whole cardigan in about a minute, and take the buttons off again before it goes in the wash.
One button, three parts
- The face Enamel, shell, metal or resin. This is the part you see.
- The shank A short metal stem on the back that passes through the buttonhole.
- The ring A small flat retaining ring that presses over the shank on the inside of the placket. Every set includes one ring per button.
Swapping in four steps
Work down the placket one button at a time, so the garment keeps its shape.

Slide the ring off the shank inside the placket and lift the old button out.

Push the shank of the new button through the buttonhole from the front.

Press a ring over the shank on the inside until it sits flat.

Repeat down the placket. Check each button is held before wearing.

Before washing
Take every button and ring off before a garment goes in the wash or to the dry cleaner, then follow the care line on its label. Keep each set on its card so nothing goes missing.
Small parts
Loose buttons and rings are small parts and a choking hazard. Not suitable for children under 3 years. Keep them out of reach of young children, and check every button is held by its ring before wearing.
