Clear Practice Lock | Transparent Padlock

It’s a decent lock for beginners, but is so easy to pick it’s a joke.

As advertised. Fun fidget toy to explore and learn how locks work. Solid construction, heavy and well made. (Don’t use it for anything needing actual security! ha)

This product is a great idea, not only providing a learning device using clear plastic for those interested in how simple locks work and getting some practice and proficiency at lock “picking”. And yes it could be a fun game. Unfortunately, the mechanism in the locks do not seem to hold up to the very sharp edges of the picks provided, leaving apparent scrapings after a few uses. It might help to have the picks de-burred a bit.

I bought this because it seemed like a good idea, especially for explaining to up-and-coming locksmiths. But I'll offer a few suggestions: 1) my lock needed lubrication - right out of the box I could not insert the provided key, even with very strong pressure and wiggling. After some powdered graphite, it works fine. But to the uninitiated, it might have seemed faulty/broken. 2) With this design, the pins cannot be changed. And since it is a visual learning aid, I'd suggest keying it with more dramatic cuts to better show off the pins lifting and falling.
I haven't yet tried picking this lock, but hopefully the machining is not TOO good so that picking a six-pin tumbler will be not crazy hard. Again, it is to show others the concepts.
Also, I don't know why you have a seventh pin slot that is not involved in the key-combination/security. I do not think traditional pin-cylinder locks have an extra pin like that. Here I guess it ensures that the key is fully inserted, but is resting on the angled leading edge of the key. Maybe that just makes it like a seven-pin lock when picking, so that much harder?
