Bundle of Three Starbucks Cups California Las Vegas Mermaid

Bundle of Three Starbucks Cups California Las Vegas Mermaid Straw is missing from mermaid and Vegas cup. Vegas cup has something on outside see pictures. I have a feeling it may be nail polish best guess. California cup is like new and mermaid cup used a few times. Vegas cup was my daughters so not too sure about it but is in good condition besides a spot of something on outside.
