Keep moisture loss to a minimum and protect the integrity of your laboratory and research applications with a flexible covering for test tubes, beakers, petri dishes and more.

Permeability Characteristics:

  • Oxygen (ASTM 1927-98): 150 cc/m2 d at 23°C and 50 RH

Pups all time FAVORITE!
Color: Dim Sum Dumpling Pet Toy Set
Our pups FAVORITE “ball”. He’s obsessed and has a blast with these little dumplings. Small size toy, but our medium labradoodle loooves them. Not to loud of an squaek either. They last quite awhile before he pops the squeaker. Fabric holds up really well.

Great squeaky fetch toy for small dogs
Color: Dim Sum Dumpling Pet Toy Set
My dog loves these little squeaky dumpling toys. They are the right size for small dogs (under 20 pounds) to chase and fetch, and they have good squeakers inside. They have a friendly look and my dog can fit them in her mouth.

Cute toy for small dogs!
Color: Pinata Dog Toy
My dog is obsessed with this toy. This does not have a squeaker in it which is great cuz she doesnt like them. The crinkles and rope seem very durable. She did eat the tail very quickly but overall its held up well! Great tug toy for a small dog or puppy!
