yes, your question i asked Helen already. She told me that i can call her to clear or can let it drop off automatically....but i think i will let it drop off automatically cuz it's still very ok even already 2 weeks....and up to now, i dropped three pcs but nobody discover it...and one of my fd i introduced to Helen also keep very beautiful...um.. i found that i haven't drop any real one, it's my own case. So, don't worry.
