I found Allu UK while looking for ways to quickly sell designer items which I don’t use. I tried their Whatsap but didn’t get a response so ended up calling their office. They swiftly booked an appointment for the next day. Very polite staff at the office who offered refreshments and got straight to business. Quickly evaluated my items and gave me a reasonable quote. They advised me that I won’t get the payment till the next day as I had visited the office late in the day. The monies arrived the next day before 11 as specified! Overall very satisfied and happy with the service.

Perfect second-hand Resell Experience!! With the international buyer's company ALLU, the whole process was smooth, high efficient. I do recommend to book a face-to-face appointment to their office at the Oxford Circus, if u have multiple items to buy or sell. Shout out to Louise Sarr the buyer, you are professional, reliable and so fun. You made the experience delight and enjoyable, thank you!

I came to ALLU to sell two Prada handbags. Matt was really helpful and ensured a quick process. He explained to me the different types of material and how it affects the market value. Would recommend to anyone selling handbags.

First time in my life I decided to sell my luxury bag, found Allu online and so happy for that! The service is amazing-I had a chat with Matt, he was so polite and patient; even I was 30 mins late he was waiting for me in the office, he carefully evaluated my bag, answered for all my questions and offer such a good price! Very professional manager, very good company. Strongly recommend.

My husband found this company online and at first I was a little dubious. After doing a bit of research I found they were a big company and listed on the stock market. We booked an appointment for the Mayfair store and from the moment we walked in were made to feel at ease. Jan was very knowledgable and a pleasure to deal with. I had no reason to hesitate it was a very professional appointment and the sale was finalised with the funds (same amount as agreed prior) in my account before I left. I’d recommend them to my friends and would use again.

Considered selling my watch after seeing an Ad and got the ball rolling out of curiosity rather that necessity.The upper-estimate given over email is exactly what was paid.The watch was collected on the Monday and I had cleared funds before dinner time in the Tuesday.This was all done remotely, super efficient and very easy to deal with.100% recommend.Many thanks to Jan and the team 👍16-06-21 Update. I decided to sell another of my watches with Nanboya. Again, absolutely faultless service. Highly recommend

I was looking to sell a couple of watches from my collection but was unsure about some dealers credibility and kept finding prices many were prepared to pay way too low, til I got in touch with Jan. Jan’s prices were very reflective of the market and he was incredibly helpful and reassuring throughout. A fantastic experience from start to finish with very swift payment made the same day.

Good people. Jan is a professional who knows his stuff and tells it like it is.The sale process was very straight forward, and funds received within 1 hour. I will use Nanboya again and would recommend them without hesitancy.

Nanboya Mayfair Store purchased my Rolex watch. It was a very smooth, efficient transaction with almost instantaneous bank transfer. Pleasurable and personable service throughout the process. You can sell to Nanboya with confidence. Highly recommended.

Tips For Increasing Selling Price

You can make an appointment by WhatsApp or go directly to our stores to sell your Cartier Jewellery.


Don't forget to bring the original accessories like an original box

The more accessories you have, such as the original box, warranty card and receipt, the higher the purchase price. Depending on the model, the purchase price may vary.


Items that have been cleaned have a chance of getting a higher price

The estimated purchase price will be higher if the item is in good condition, so regular cleaning is recommended. Wipe off the various traces with a soft cloth.


Sell ​​Cartier that are no longer used as soon as possible

In principle, the older the item, the lower the purchase price. If you are not using it, it is better to sell it before the purchase price drops.
