I've worn this out twice for maybe 2 hours the first time and 4 hours the second, neither of the times it was in the sun longer than thirty minutes. 
While I love how cute this purse is, it makes me too nervous to wear out and I just can't get myself to wear it out for fear of ruining it. 
Selling it for around what I paid after shopping service fees and shipping from Japan. I'll ship it in a box with bubble wrap.
