Personally, I would not purchase a canvas bag right now. I would wait for them to rectify the problem. Clearly this is a universal defect with the mono canvas line and it needs prompt adjustment.
I'm sure they would offer an exchange if it does happen, I have no doubt about that. But I wouldn't want to go through the hassle of perpetually checking over my bag and then having to bring it back if it starts to look like a hot mess. I'm not that desperate to buy a purse.
Sorry, I don't mean to sound negative. I'm just irritated. I bought the Mono Artsy a month ago and noticed peeling the day I got it. Needless to elaborate, it went straight back. Poor Linene, she's been through like 2 of them already. Or was it 3? Sorry, I lost count.
I hope you get a perfect one without any issues. On the bright side, you have vigilance working in your favor, so if anything does happen, I'm sure you will notice right away.
