Bottle cap collecting
# Bottle cap collecting

Bottle cap collecting is the hobby of collecting metallic crown caps. The hobby may or may not include drinking beverages that have been sealed with crown caps. Opening bottles with traditional openers may damage the crown caps, thus some collectors use automatic bottle openers to avoid any substantial damage to the crown caps.
