I was scrolling through Ebay looking at new devices and came across a cheap plastic device with this locking type. I'm very intrigued by this as it uses the plastic locks with a plastic magic locker piece. Very Interesting. Would love hear you guys thoughts. https://www.ebay.com/itm/363631737169?hash=item54aa23f951:g:-IgAAOSwWHRhnKqO
The original is called the AirLock, created by Kink3d, non-metallic so it wont alarm in airport security. Obviously you need a non-metallic cage like the kink3d mamba. Worth exploring, though, especially if your self-control is strong
I like these over traditional locks. Instead of using these lock tags, I keep it secure with a small zip tie.
