Beautiful leather and great quality
Beautiful leather and great quality however the first time you try to attach it to G Line it is very tight fitting and needs to be heated and softened a bit to get it on.
Heavy Duty Leather Carry Handle for Brompton Bicycle

Probably the best bag you can buy for your brompton
Goes very well with my green g-line. There's no need to say much about the quality—it's simply perfect. What I line most is that when not mounted to my Brompton it‘s just a very, very stylish bag.

Very quality product
Very quality product. Marketa is so kind and helped track the order throughout. The money clip itself is good leather which can hold a lot of bills and a few cards. The look is exactly as they displayed on the site. Very happy with the product.

Protecting my G Line
My G Line started to show a few scuff marks on the frame so I thought what can I buy to protect it from further damage. I found soumaleather.com and following a quick email, Marketa replied to say that they could make a long frame cover but it would take a couple of weeks as they had not made one for a G Line yet. Shortly afterwards, Marketa emailed to say that I could place an order. Talk about a bespoke service! Easy to fit, once you have looked at the video and got your head around the pattern of stitching; looks great!

Fantastic quality leather handles and great customer service
Fantastic quality leather handles - second purchase as i had ‘accidentally’ sold my old pair with my other Brompton.
Really like the fact that they accept custom orders as I needed to reorder a missing part. Very fast and friendly service- been a customer / fan of Souma for at least five news now - always customer focused.
