"These 12" long, glass, wood screw top storage containers were a perfect fit for our unused, built in, horizontal, metal wine rack with 3.5" holes in our RV while stationary. The containers' 3.5" diameter fit perfectly except for one of the three glass container's circumference was slightly not perfectly round. Although not visibly noticeable, it did require a little sanding of the paint in the wine rack slot to fit the container into the holes in the rack. The other two containers fit perfectly without modification. The included thicker replacement silicone ring cap seals do stay in place better. One of the container's glass threads for the cap were slightly malformed such that a cap would spin off if tightened as much as the other two containers. Overall a great dry foods storage solution for our wine rack."
