Supporters within the USA should keep an eye on tracking updates. This reduces package theft, helps with mail claims, and (if you purchase shipping insurance) enables timely Route cases. Please read your credit card agreement — most providers offer online order protection, including package theft / loss insurance.
Finally, inspect each item upon arrival. Most keycap manufacturers complete quality control and keycap packing / sorting (into plastic trays) by hand. That means even the most expensive keycap sets can have duplicates or misprints — much like other bespoke products.
Please contact email@example.com for assistance (it might take some time for us to reply). If we don’t have your keycap on hand as a spare, it will take 2-5 weeks for us to dispatch a replacement. We try to make bulk replacement part requests from manufacturers — single-item shipments tend to annoy our contacts.
