Like the product it encases, HollenWolff packaging is beautiful, highly-engineered, made in the USA, and layered in meaning. Cufflinks and shirt studs are encased in a rich Horween Chromexcel leather traveling case, with studs secured in a holster beneath the cufflinks if included. This resides inside a keepsake leather-belted anodized aluminum housing, numbered to match its set, and personalized laser-inscribed messaging as desired. Finally, all is secured for shipping and presentation inside a renewably-harvested and aromatic red cedar valet.

Clean with mild soap and water for periodic removal of dust and debris. Shake out excess, air dry or blow dry (for example with compressed air) and polish with the included microfiber polishing cloth. Buttons/screws are bonded and mustn’t be removed. As such should spin on the male links in unison with the opposite slotted end outside the ball retainer. If screws are noticeably backing out of links or for any other concern, please contact us for complimentary return, repair, and/or replacement as required. When not in use, cufflinks should be stored in their leather traveling case.
