One of my buddies got two abcesses from not being as sterile as he should've been and trust me if you would've seen him shaking with a fever and chills puking his guts out for three days and not being able to lay or sit on his glute or thigh where the abcesses were until the antibiotics kicked in you wouldn't ever even think about reusing darts. not worth it man go to getpinz or anyone else and do it the right way.
