Review on Leakproof Silicone Refillable Containers Squeezable by Tammy Griffin

They hold up well and are waterproof when I take them on hikes and throw them in my duffel bag and they don't spill. I left product residue in one and left it in the car for a week and this one didn't clean well enough and I had to throw it out. They're a little tricky to clean, but a small bottle brush or the "fill with soap, roll and squeeze" method works for me. They also eject the product with good pressure.
