Fills all my holes with ease lol , great size variety
A great product to fill holes with! I have used these for a couple of things around the house I love that it provides a variety of sizes. I’m currently using one for my sink in the kitchen. The bathtub for the kids and our water table outside. So many sizes and gives great options for all the holes you need filled

Solid rubber plugs that have several sizes
These black rubber plugs are best used blocking for water and similar liquids as it seems petroleum products want to eat thru the rubber. In that case get silicone plugs. For everything else this a great assortment of sizes.

Read before you buy.... (How many come in each size?)
Okay set, but I wish the description had been more clear about how many of each size you were getting. I was looking for x2 of the size #6 and of course this set came with only duplicates of the really small sizes. All the larger sizes only came with one each. I had to return.

Great Planter Drainage Stoppers
These work great as drainage hole stoppers for my indoor planter pots, both as replacements and for planters that I have drilled holes in. The stoppers are easily trimmable which is helpful for planters without feet.
