I used these Walnut Button Top Plugs for a project 8 years ago and needed the same for a current Project. They are sized perfectly. I used about 4 coats of clear coat on the tops and 1 coat around the inside of the holes they were going into, a super tight fit. If I ever need to take them out I'm sure they will pop out easily. Selection is way good and shipping is very fast. WidgetCo is my go to for custom plugs.
