Good quality, but the price is too high

Tal cual se describe
Es un tapón totalmente metalizado, se ajusta perfectamente a mi botella de la misma marca. Lo Iñigo que espero es que no se oxide, tengo varias botellas de esta marca y todas fenomenal. Lo recomiendo

Just what I needed
Found this steel version after I dropped my Hydro Flask and broke the plastic cap. Could be a bit cheaper, but if it lasts I'll be happy.

Works as Intended.
Perfect for people who does not want to use the default plastic cap and want a all metal Hydro Flask Bottle.

Better than the Plastic original cap
As this is a stainless steel cap , it hold the warm water for at least more than 16 hours where else the plastic cap can only hold less than 8 hours which make it worth every cents . Highly recommended without worry ..

Very durable and good looking
Bought this to replace the plastic one it came with because it cracked. It’s very solid, looks great, and i had no issues closing it with the thinner Hydroflask bottle. It matches really well with my stainless steel one.
