Benzotriazole is used as an organic antifoggant and density depressant in developers.
- Benzotriazole acts as a restrainer without affecting other properties of the developer. It can also be used as a fog restrainer when processing out dated papers
- When blue-black or cold-black image tones are desired with bromide papers, benzotriazole should be used in addition to, or substituted for, potassium bromide
- Make a 0.2% solution of benzotriazole (2 grams benzotriazole in water at 125°f/52°c or higher to make 1 liter) then reduce the bromide to 1/10 or 1/6 strength and use just enough Benzotriazole solution to prevent developer stain or fog. A little experimentation may be required.
- The same treatment can be applied to chloride and chlorobromide papers to eliminate any greenish black tendencies and/or achieve a blue-black tone.

SOOO DURABLE!!!
Pattern Name: Tug Rag
VERY VERY VERY durable!!!!! I have a Malinois and a Cane Corso who are both very high energy and high intensity. They have shredded every single toy, bite rag, and rope ive purchased butu this one has stood strong for a year so far. i would 100% buy again. could also just be thrown in the washer if it gets dirty which is a HUGE plus for super droolers.

poor durability
Pattern Name: Squeaky Toy
my dog pulled the strap off in under 10 minutes.
The leather is not sturdy and my dog was able to tear it to pieces in 20 minutes

Ok but not Leather
Pattern Name: Tug Rag
I will say it's fairly durable but when the description uses the word leather..one would expect LEATHER, not microfiber. That said..it is thick and pretty durable and the dog does like it ok. Obviously the strap is NOT meant for chewing. This is not a throw it on the ground and let ur dog have it sort of a toy. It's an interactive toy. If left to the dog most would scissor the strap off in the first 10 minutes. Something to keep in mind. In summation..an ok interactive toy but over priced for the material.

Well-made and great size for the price!
Color: blue black
Very tough product, no odor of plastic, good toy for outside, perfect for medium or large dogs. Noise isn't too bad and the color is cute as well. Can't destroy this toy!

Durable Great for aggressive chewers
Color: Blue
Will make one whole room smell like fake bacon, but my dogs love it and it’s super strong and durable. I have a lab mixed with rotty and a full lab so it’s a perfect match.
