Medium Qarl -- Medium silicone -- Q-751 Squishies Circumference of the long tip:

Circumference of the long tip: 2

Useable length of short end: 4

I would have liked to let these sit longer before shipping them

It is not unusual for this toy to have an occasional bubble on the side of one of the vines

3) I don't believe there should be any problem with silicone touching the acrylic spray we coated these in
