This Nunoo open-top tote has been a great success. I bought it at a sample sale and it is the perfect size and shape for work. It is medium-sized rather than large, so I am unable to overstuff it. It is big enough to carry a jacket for autumn weather. It does fit my laptop and A4 pages but I try not to carry much these days. The leather is very lightweight but also durable.
Here I am using it with my H&M x Kenzo keyring
