The listing, ScaldScafe - Water temp tester has ended.
ScaldSafe Baby/Warm/93.2 degree F - ensures that bath water is at a safe temperature for your baby. Non-toxic. A must for parents and child care providers.
"1. Run the water: Drop or dis the Scald Safe disc into the hottest part of the water, or blend water first.
"2. Check ScaldSafe Color:
If disc is purple, the water is below 93.2F
If disc is tinged with pink, the water is 93.2F and safe for baby to bathe.
WARNING - if disc is bright pink, the water is too hot for the baby (over 93.2F). Adjust water temp as necessary."
"The ScaldSafe disc may be left in the water for constant monitoring. When cooled, it quickly returns to its original, purple color and is ready for re-use. Note: Do not expose to open flame or cleaning solvents. May be cleaned with ordinary soap. Keep the disc away from prolonged, direct sunlight to ensure years of reliable use. Store dried disc in pouch."
I am not sure if this has ever been used or not - so I will call it "used." But looks to be in perfect condition - pouch included.
