Residential Antifreeze 5L x 2-piece set Furukawa Chemical Industry KYK

Furukawa Chemical Industries KYK
Residential Antifreeze Torun Blue 5L
Set of 2

For preventing freezing of toilets, drain traps, entrances, and doors.

I bought this for home use but never had the chance to use it.
I'm offering it to someone who will use it.
The photo shows one item, but this is a set of two identical items.

Will be packed in recycled cardboard.
