Or send him a packet of straws, and tell him you couldn't afford to send the teeth!

Those dang things are expensive so I would do the baggie thing, and make sure to add something in the box to protect them from breaking.

I would check with a local dentist and ask for his suggestions and he may even package them correctly for you. Should they break they would be of no use.

you could pack them in a baggie and place the baggie inside of an empty coffee can but pack the can with stuffing this way they will receive no damage to them. i ship a lot of weird things and a can is the safest way.

I just had to post this. My brother put his picture on his Facebook page, with the caption "Now I'm pretty again!" Thank you all for your kind help with this.
