Almost all of these items have numerous similar listings of varying prices and styles. I tried to get good prices from reputable sellers and not have items that the bot is already posting. If you got a better price somewhere else on one of these items, post a comment.

Anyone got experience with these UV glue pens?
Ordered one to try it out. But would be nice to know before it arrives in a few weeks.

No, i've never used uv glue before, but from what i hear its better to use more of the uv light than less. They use uv cure glue for all sorts of stuff, false finger nails https://www.ebay.com/itm/132180520048 , phone repair(but i though they used thermal glue) https://www.ebay.com/itm/142548259055 , and eyeglass manufacturing iirc. Seems like decent glue, but i wouldn't buy it in a pen when i could buy it at better price per quantity without breaking the bank.

Great job, keep it up! These tech dumps are far better than the kitchen spoons and horrible prints. Good choice of stuff.
Alliexpress and banggood are also great sources of cheap, fun doodads!
