AliExpress unbagging joy - UVC light, weird pens, Ignition electrode, RF relays and more

Another courier-carnage of technical goodies from AliExpress for us to explore.
This was filmed in work-provided accommodation, so it will look and sound different.

These videos are not sponsored by AliExpress. I buy all these items myself.

Here are some links to the items. These are affiliate links, but that will not affect the price you pay.
Keep in mind that these products may not meet your country's standards.
Some listings may not work for some countries and some may just be sold out or disappear.

When paying on AliExpress, let the transaction complete before leaving the purchase page as otherwise it may not go through.

UVC germicidal light:-

Be VERY careful if you get one of these. These lights are designed to sterilise cabinets by emitting shortwave ultraviolet light that destroys bacteria, viruses and just about anything else exposed to the light. If you view the tube directly with no eye protection then there is the risk of "arc eye" (photokeratitis) which will cause extreme discomfort after a delay. Your eyes will recover quickly, but it's a horrible sensation. The UVC can also cause serious skin irritation like sunburn.
