with mine i was asked if i wanted to keep it (i am of maori descent) but i declined - it was used for DNA testing for the girls (to check if they were ID or fraternal) and has since gone on to be donated to help others (as the blood can be used for leukamia patients) - it's a pretty cool thing to look at - mine was big enough to fill a shopping bag lol amazing to think that something that looks so well gross sustains a human life
