The buttons measure approximately 1.5 cm and are about 5 mm thick.
The buttons can be washed inside out at 30 to 40 degrees, but not in the dryer. If you want to be completely safe, you can wrap the buttons individually on the garment in cling film before washing. This protects them a lot. But as I said, delicate laundry without a dryer is totally fine.
Please note that each button is unique and handcrafted, so they are not 100% identical.
