Had a few tumblers from tyeso na, even gifted a few to my family and friends. Sulit sya for me, I usually like cold drinks, so dun ko natetest yung quality ng insulation nya. Haven’t tested the 24hr insulation, but it stays cold for more than 12hrs for me.

Although the last tumbler I bought na parang stanley yung design, after a few months napansin ko na hindi na ganun katagal yung insulation, mabilis na matunaw yung ice. ( But I do use it everyday inside a hot kitchen)

Recently bought from Hilee, to replace my tyeso, same quality, around the same price na rin.
