This is a set of 5 toy syringes that contained mizuame (Japanese syrup). They are colored and do not have markings. Please consider these as toys. Great for playing with colored water, slime, or pretend play. If you would like to buy them individually or have a color preference, please comment. *I have washed them thoroughly with detergent, dried them, and stored them, but please refrain from purchasing if you are concerned about cleanliness.
