## Customer Reviews

### ⭐⭐⭐⭐⭐ A CORK IS A CORK IS A CORK ... WELL KIND OF
*by A***R on February 25, 2021*

They were true to fit. used them to plug holes in bottom of planter pots (garage sale items) and a old bathtub ... true to size and hold well ... suggestion if using them to plug a hole in wood or in pots use silicone glue around the top and about a inch down before inserting them ... that makes sure there is a good seal.SPECIAL NOTE: FOR THOSE WHO DID NOT GET EXACTLY 100, REALIZE THE MANUFACTURER USES WEIGHT THAT EQUALS 100 CORKS IN THEORY SO YOU MAY HAVE LESS OR MORE DEPENDING ON THE CORK WEIGHT.

### ⭐⭐⭐⭐⭐ Perfect
*by C***N on October 17, 2020*

I used them for 5ths I turned into portions and they worked perfectly

### ⭐ Leaks!
*by A***S on October 30, 2020*

Bought these to make wine. When I bottled I noticed that chunks are broken out of the side of these corks.When pressed in to the bottle and turning sideways they began to leak.Disappointing. Bought these because the vendor stated that these were made in Portugal. Was hoping these would be of a decent quality.
