Does anyone know if the button type for them is specific to those jeans or are there similar ones in the same era of them? Have found a few the same size and logo shape but looks like they are more prominent in the depths on the grooves

1 inch button

Button came off as it got ripped really hard as i sat on a bench on my RICKY SUPER QTs. Is it fixable if so how if not how can i find a replacement ?
