Review: Quality bag - Such an amazing quality bag really good for my HP Elite notebook 830 G7,, Iam loving it
Review: Perfect for tablet owners - Got the 12 inch sleeve. I was able to fit my Galaxy Tab S7 (inside a folio case) with Logitech K380 keyboard and Pebble mouse. There's also an outer pocket that fits my phone, airpods and 10K powerbank. Inside material is soft and outer material feels a bit harsh. Removed one star due to the zippers as they don't feel like they would last long but I will provide an update in the future.
