Unfortunately...
...I am forced to give this product the lowest possible rating. The lids do not fit securely and water slowly seeps through the bottom seams of the cups before my tea can steep. I normally buy 16 oz cups for myself/adults, but purchased these for my 6-yr-old granddaughter, who always wants me to make hot (warm for her) tea when she comes over. If you're using this cups for non-liquids they will probably be fine, but for beverages these cups, at the least, make a perfect mess, but more importantly could cause someone to be burned if using them for hot beverages.
