Timbuk2 Duo Convertible Backpack Briefcase 3420-3 Night ShadowA briefcase with backpack straps does not make it a backpack. The Duo is a briefcase first and a backpack a way distant second. Its hidden backpack straps untuck when you need them and disappear when you don't. So when you stroll into a board meeting with this fresh take on a traditional briefcase, no one in the room will know you were running down the street with it on your back seven minutes ago. Refined menswear twill and leather details are paired

So far so good!
Color: Silver+Brush Holder
It’s only been about a week since I applied it, seems sturdy enough, and the adhesive was sticky enough that it seems secure. I use very hot water to wash dishes due to illnesses and it’s held up well to the heat of the kitchen thus far using just adhesive. Good buy!

Suction cups aren’t the best
Color: Black+Smiley Face
The suction cups don’t hold and my smiley sponge isn’t snug on the post so it sometimes falls off.

Sticks and stays in place!!
Color: Black+Smiley Face
Love love loveeee this! Took me a while to find one that actually sticks and stays in place.
I've had mine for a few months now. Looks just like the photos & comes with the suction cups and an adhesive strip if you want a firmer hold.
The suction cups work just fine.
Would recommend 👍🏾😁
