SCP ideas (I'm new sorry if this is a bad post)

First off, new to the site, love the concept and such and think it's super interesting. Seriously, you all do great work I hope to be a part of

As for my SCP ideas, they're pretty basic I've gotta flesh them out but here they are:

Mostly a joke SCP, a really round stone that people who see feel obligated to take with them as a souvenir, put it on a shelf, forget about it, and yet never throw it out ((this may just be me but for he longest time I'd see super round stones in beaches and think "I've gotta take that" for no real reason))

Second one is a pencil, whenever someone uses the SCP they are then pulled into a trance of drawing, often dying of exhaustion and malnutrition. The pencil itself seems to be the one controlling what is draw. The person will keep drawing even after they die and only finally collapse once the pencil runs out of graphite. After an hour all the pencil markings will disappear from wherever they were drawn and the pencil will reappear perfectly intact. It has no eraser. ((Possible add-on, a demonic face appears every time a new person begins to draw, and in each subsequent event the face gets larger))

Again, super sorry if these are bad ideas or taken ideas or this is a bad post
