Perfection personified

Customer service was exemplary and the items received (keyrings & pen) were delightful. The engraving was excellent and there are many happy recipients of Wingback items that will undoubtedly treasure them forever! Very happy customer.

Excellent service from new company

The whole experience was excellent from the moment the order went in to delivery. I would certainly recommend their products.


In the past year I have purchased the mechanical pen and pen holder and the key cachet. Each are beautifully made and presented. The ethos of longevity really appeals and these every day pieces will certainly last a life time. I shall be adding to my collection in the future for myself and as perfect gifts for family and friends.


MY BEST TOOL FOR WORK RIGHT NOW IS MY WINGBACK PEN - I also own wingback wallet and notebook cover - high quality feel good products - I have also bought for gifts which have gone down very well. The service has also been superb - getting me out of a tight spot when I forgot a present for someone. Highly recommended.

Fragile as all get out

As the title says if my pen rolls off the desk or I drop it, the pen magically always lands point down (mechanical pen—brass)and the cartridge cannot handle it at all I’ve run through 5 cartridges in a week simply because I’m clumsy. I’m currently searching for an alternative filler if you use these cartridges buy them by the handful

Hi, Sorry you're having trouble with the Fisher cartridges. As an alternative to the cartridge you can purchase an adaptor which will allow you to use any D1 cartridge instead. We don't have any in stock at the moment, but if you search for 'Schon D1 adaptor' online you should be able to find one fairly easily.
