In the Variation Monster plugin, you can customize the width of the icons shown on selected and disabled variation swatches. For example, if you want the checkmark (✔) for selected variations or the cross (✖) for disabled variations to appear bolder or thicker, you can increase this width value. This setting gives you precise control over the visual appearance of these icons, helping you match your site’s design style more effectively.

After change this width you can show it in archive page and single product page like below this image
