Suiwotin 60PCS 10mm (3/8") Black Hole Plugs Plastic Flush Type Hole Plugs Snap in Locking Hole Tube, Furniture Fencing Post Pipe Insert End Caps (Black)

Perfect! Spot on diameter and durability to cover the holes in a manhole cover in my driveway to keep the bugs from exiting the storm drain at night. Easy to remove if/when access to the cover by the city is needed.

My package was damaged. Some of the plugs were loose and missing half of them. It wasn’t worth sending them back.

Worked as described. Plugged a hole.

I am using these plugs, along with vinyl caps and rigid plastic tube to store small drill bits. The plugs grip the tubing and provide a secure bottom for the container.
