Review on Spooktacular Set of 50 Halloween Blood IV Bag Reusable Energy Drink Containers - Perfect for Zombie Theme Party Decorations, Complete with Syringe and Clips - 12.6 fl.oz by Karoly Reddick

I've tried 3 different packs of these blood bags from different vendors and these are the worst. The plastic is very sticky when you receive them so they are difficult to fill and although I filled them the same day as the party and immediately put them in the fridge my shake tastes like plastic. You definitely get what you pay for. My guests enjoyed the novelty and drank them all and they actually worked as expected (apart from the refill issue - and by the way I'm a nurse so I'm pretty good with syringes, drawing up liquids and filling bags) but I would do it t bought them again.
