Non-metal Device Options for Frequent Flyers

Good evening all:) Over the past few years, I’ve been using a Steelworxx Crossfire made of metal and have always been pleased with it. However, I need to purchase a new device for chastity. Because my job involves frequent flying, I unfortunately won’t be able to continue wearing metal devices. I plan to wear my chastity cage 24/7. Cleaning ease and comfort are absolutely critical for me. In my opinion, plastic belts and cages (for example the CB6000 which I tried previously) fall short of the minimum standards I expect. What about silicone options? Could anyone recommend a completely non-metal chastity device suitable for 24/7 wear? A numbered plastic padlock could serve as an alternative to a traditional metal one with a key. Please don’t worry about cost; feel free to suggest any type of device, regardless of price. Thank you very much in advance
