### ⭐⭐⭐⭐⭐ Good quality seal set
*by L***C on June 24, 2025*

I adore these stoppers. They fix what the premium cup “brand” couldn’t or wouldn’t. Stops all leaks. Fit well. Works well. Nice color. They will create a much stronger suction when drinking from the straw. I use a silicone straw and will gently press the straw away from the seal wall in order to let a small amount of air flow through to help offset the internal pressure. These seals are awesome.
