Keychain Holder, a keychain designed for synthesizer enthusiasts, inspired by Vaemi’s oscillator OSI-OP design. The Keychain Holder works with an adapter. It has a fitting at the top that allows it to be hung on the wall. The design includes lights. While the Vaemi logo in the center stays lit continuously, the Vaemi text above the jack inputs lights up one by one as you plug in the jacks. The product comes with 5 jack keychains. You can attach these jacks to the keys you use daily, and when you arrive home or at your workplace, you can hang your keys on this holder. The knob helps you adjust the overall brightness of the lights. Additionally, there is an On/Off switch.
