I purchased this for my parents to use, but I am selling it because I only used one and the size was different. I purchased three boxes, two of which are new and unopened, and the remaining 24 syringes in the other box are also new and unopened. The expiration date is "January 2029". I will consider selling individual syringes if you wish. Terumo Catheter Tip Syringe SS-20CA20P
