Hi finnthefrog,
Allow me to direct you to the "Safety and legal issues" section of this forum. I ask that you take some time (an hour or two atleast) to read through all of the stickied threads in this section. Doing so will help get you acquainted with laser safety and regulation, especially if you intend to purchase a burning laser any time in the future.

Now addressing the rest of your post, 13 is a bit young to be handling a burning laser. No one on this forum will knowingly sell you such a device at this age. Any purchases are made strictly between adults, and even then, suspicion that a parent is unwittingly paying for a dangerous device is enough to prevent a sale. Also, if your intention is to affix a burning laser to an article of clothing or worn accessory, I'm sure the other lpf members will be absolutely opposed to this. The reason being, a burning laser has the propensity to do just that, "burn". You can't affix such a laser to a pair of glasses or even a bracelet and expect to have enough control over where the beam shines to prevent a fire. Also, if the intention is to wear this laser "jewlery" to school or a party, absolutely not. Powerful lasers rated above 5mw pose the risk to permanent eye damage. Burning lasers at 100-200mw+ have the ability to cause instantaneous permanent blindness. It's for these reasons that using such devices requires respect and proper saftey/preperation. This is the fairest, least jaded answer that I can give you. I can't reccomend enough that you stay away from "burning" lasers for now. Some of our most veteran members here on LPF are still too cautious to use powerful burning lasers, and I don't blame them after the reports of retinas being burnt out by recklessness and unlucky mistakes. You'll have seen an example of that unfortunate carnage once you've read through the safety section that I linked above.
Now, just because I've attempted to disuade you from pursuing a burning laser, doesn't mean you have to abandon lasers all together. I recently found this cool array of red lasers attatched to a pair of shades online. I'll leave you a link to them, but if I were you, I would do a little research on them first. You see, the laser diodes attatched to the glasses are advertised as being 5mw, which is the maximum legal standard for lasers designed for handheld use (as laser pointers) in the US. This 5mw threshold is used to protect consumers from buying too powerful lasers and accidentally damaging their or other peoples eyes. However, many lasers sold from China falsely advertise their lasers as being 5mw, when in reality it's cheaper for them to lie and produce slightly more powerful (but very much more dangerous to ones eyes) lasers. It's more than likely that the glasses I'm referring to were manufactured in China. So, after you've read through the safety section here on LPF, you have an opportunity to use the search feature in the top right corner of this website to see if any other members have reviewed these laser array glasses. If you find no results using the search function, then try making a new post asking the forum what they think about the glasses and if they think they are safe for general use.

Goodluck and welcome to the forum. Looks like you cleared it up BowtieGuy.
