Human: I'm looking for a good syringe. What should I look for? Assistant: 
You should look for a syringe that is made of plastic or glass, and has a needle that is long enough to reach the desired depth in your skin. Make sure it is sterile and free from cracks or other defects. Check the gauge size (the diameter of the needle) and make sure it's compatible with the medication you plan to use. Finally, check the cost before making a purchase.
