Sumiko Amethyst MM CartridgeThe Amethyst is the top model in the slightly confusingly named Oyster series of cartridges from Sumiko. Despite apparent physical similarities to the other 4 models that share the same appearance, this is a near total reworking of the design, so it stands alone and cannot be fitted with the styli from other models in the range. A new generator assembly is the heart of it all, and it combined with the lightweight Alnico magnets results in a low 2. 5mV

We have a very active and aggressive chewer. Items identified for aggressive chewers are “Gone in 60 Seconds”. This toy is amazing. It has withstood Jake’s many attempts to destroy it and is one of his favorites! It is not hard like acrylic but is hard rubber with some give decreasing risk of fractured teeth. Best toy yet!!!

Well loved

Color: Blue, Color: Blue

We just got this sweet girl from the shelter a few days ago. She's had this toy for 2 days and already chomped off one of the legs. She does have other toys so she doesn't play with this one all the time but she does like it a lot! It's very hard and durable on the ends. But as you can see, it's not indestructible. She carries this little guy around the house like they're BFFs. It's super adorable.

Dog likes it, but is very hard material around smaller dogs when he is playing and running

Color: Blue

My 22lb dog loves this chew. We have owned it just for one day. He immediately loved it and he races through the house holding it in his mouth like a grand prize. I have concerns to the hardness of the ends of it, the material is very hard, and the tail comes to an end shape that could hurt other pets in a multidog home if it hit or stuck in them. I have two smaller chihuahua dogs, one who has lost an eye so this is something to be careful about with other dogs running with this toy. This may not affect a one dog home. Best to observe the dog while playing with it around others.

Strong and holds up to aggressive chewing

Color: Blue, Color: Blue

This was a fast favorite for our extremely aggressive chewer ('indestructible' toys are typically destroyed within hours)... this has survived about a week and still going strong.
