Last Fall we bought these:
And finally got around to trying them. They are sturdy silicone and flexible. The lids go on and off easily. We filled ours with Great Value brand strawberry yogurt, the kind that comes in a 32 oz container at Walmart. We laid them on their side in the freezer and since it was thick stuff, nothing leaked. If I were using juice, I’d prop them up in a glass or vase just to be safe.
The lids came off easily. My 5 year old could do it without help.
The pops were hard to push up until the heat from our hands softened the outside a little.
Yummy. Mess free. And I know what’s in them.
“Do I get one too, Mommy?”
