A keychain store handles everything in-house from consulting to making the keychain. In-house firms do 3D printing of models, sample testing with metals or rubbers, and logistics. Their readiness for the market is guaranteed through ISO 9001 certifications, REACH certifications from the EU, or CPSC certifications from the US. Their clients’ concerns are attended to in different languages so they understand different cultures such as Middle Eastern Arabic Calligraphy which is useful for their clients from the Middle East.
