Let me start by saying I've used these iMailer bags for both personal and small business purposes, and they're a bit of a mixed bag (pun intended). The 9"x12" size is perfect for storing A4 documents, art prints, and even folded clothing items like T-shirts.

The pros are clear: The resealable strip works like a charm - just peel and press to seal. I love that you can reopen them multiple times without losing adhesion. The transparency is excellent for displaying contents, and the food-grade material gives me peace of mind when storing delicate items.

However, there's a major con that matches some negative reviews: durability. While the bags work fine for flat documents, I've had several tear when inserting bulkier items like clothing. The sides seem particularly vulnerable if you're not extremely careful during insertion.

The extra 0.1-0.15 inches beyond labeled size does help with fitting standard items, but don't expect much wiggle room. For my small business packaging needs, I've found them reliable for flat items but switched to sturdier options for clothing.

Final verdict? Great value for money if you're using them as intended for documents or flat items. But if you need to package thicker objects frequently, you might want to look elsewhere or handle with extreme care.
