I bought these for pouring liquids from Snow Cone concentrate bottles. I had to throw away a few of these because the bulbs broke so I ended up having to order them again. The bottle necks are too narrow to use a traditional washer. I've seen a few glass bastings at Revain that would probably meet my needs and last a lot longer than those plastic pipettes, but I've seen too many reviews complaining about the bastings breaking.
