Good 1/2 inch teak plugs, bought 1500 for my sailboat deck. I added the pic for those not yet familiar with thier use. LHS, ready for new plugs, RHS, some original ones with teak plugs in place.
These appear well cut and have a consistent appearance. I really like the chamfer on one end, makes it easier to start them into the hole.
These look like teak, and I ve used quite a lot of wood types, probably right; can't say 1 about source and sustainability.
Best price, glad for this bulk sale!
