If it's sueded, you won't be able to use the meltonian on it, I don't think. That's for smooth leathers.
I'm wondering the same thing actually - I really want that iridescent light gold mini (the duochrome gold - taupe - pink one) and it seems like most are sold out, or are very hard to find. Does Chanel typically replenish their seasonal stock through the next few weeks, or is it just a one-time stock, and if it's sold out, it's gone forever.
I work in a Chanel boutique. It's pretty difficult to get a mini because there is an established waiting list and each location receives a set amount (for example, my boutique received two black, two red, and two grey). Once those are sold (usually to the people on the waiting list) we don't receive additional stock and we cannot order additional stock.
