Seekingtag Clear Fillable Ornaments Ball - Pack of 12 Individual 120mm Ornaments

Would 3 lipgloss products fit in here?

How many ounces of m&m's needed to fill the space?

I want to put a pair of adult socks, trial size lotion and a chapstick in each one would the 100 mm be a good size?

Are these leak proof after closing or locking? I am planning to check if I can add some fake snow and glycerin.
