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