Isolierflasche Ersatzdeckel

The twist-on seal is exactly what I needed—I’ve chucked this in my tote twice now and not a single drop escaped. Fits my older bottle perfectly, so it’s nice to finally have a backup lid that doesn’t leak.

Spilled coffee all over my bag last week because the old lid finally gave out, so this twist-on replacement was a relief. It threads on smoothly and I've tossed the bottle in my work tote three times now without a single drop.

I was worried about finding a replacement that actually seals, but this one threads on snugly and I’ve tossed my bottle in my work bag twice now with zero drips. The fact that it fits every size in the line is a nice bonus if you’ve got a few floating around.
