Seedor is cool and all (they look nicer maybe), but you can do something similar on your own. You will pay more depending on the steel specifications (heat tolerance, corrosion, etc), but buying the best I could find cost very little in comparison to something like Seedor.
I spent around 50USD for the punch kit (hammer, letters, numbers, platform) and all the materials needed for the steel backups. You can tailor the amount of materials to lower the price. I bought quite a lot to experiment.
I'm fairly public about my journey in Bitcoin, but ordering parts like this or going to a hardware store can naturally be a lot more private than ordering a kit from a Bitcoin company.
One disadvantage is that I didn't have a guide to help with stamping, but it wasn't that difficult to freehand. I'm sure there are kits with guides or whatever the technical term is. You could consider engraving.
I haven't looked for a steel capsule yet, but I have seen them on keychains for holding medication. I'm sure something exists.
I haven't done this, but I have considered cool hiding ideas for these. You could easily install it on something like a vehicle (with the bolt head flush and in view) or something else that is double walled and most people would have no clue that it's a hidden seed.
Seed backups is a pretty interesting topic once you start experimenting and thinking about it.
Have fun.

NOTE: THIS IS FOR PEOPLE WHO CAN'T AFFORD THE SEEDOR PRICE, WANT MORE PRIVACY, OR HAVE SOME OTHER NEED.
I don't care if you like Seedor and own their products. I just used it as an example because it is the closest popular example I can find like this sort of backup. My goal is to give people a cheap and private backup option, not to attack Seedor or any other product. Use whatever you want.
