Hello Ladies, I’m new to lambskin and I need you guys to help me. I purchased this Trendy CC in January 2017 and by the end of the year, I started to see air bubbles at the bottom of the bag. Is this normal wear and tear for lambskin?? This is my first lambskin piece. I know lambskin need higher maintenance and I expected to have scratches but not air bubbles or does it even call air bubbles??. I stored my bag in dust bag and lay it flat in my closet, no direct sunlight. I only used it few time throughtout the entire year. I really really love the trendy cc style but they only come in lambskin. Please share with me on your lambskin Chanel aging process and if you have the same Trendy CC, medium size, in navy blue, did it happened or happening to you?? Thank you Thank you!!
