Lang Stereotest I-R
The Lang Stereotest I-R is suitable for binocular diagnosis and screening of stereo vision disorders in young children of pre-verbal age. This test is the revised and improved version of the Lang Stereotest I named after the Swiss ophthalmologist Joseph Lang, as the optical and printing quality has been improved. In addition, this version has no monocular clues when used correctly.
The Random Dot test card is provided with three random dot stereo objects in different disparities. The test is performed with a reading distance of approx. 30 - 40 cm, without the additional use of glasses to separate the visual impressions. This allows the child's eye movements to be observed without restriction.

This version is ok, but NOT for my boy-The 24in Jumbo version is the perfect toy for Kota-Ghost.
Style: White, Size: 24" Jumbo, Style: White, Size: 24" Jumbo
Adorable & nice but...
I hate writing adverse reviews but I had to for this one. It lasted exactly 1 minute.
30 seconds of that was Ghost pulling the rest of the stuffing out to completely gut this Lambie.
I know what happened-The material on the chest and the little red buttons were the issue. Cute as it may be, that material is terrible. My Great Pyrenees/AmStaff/Golden Retriever Mix boy, Kota-Ghost, very rarely tears his stuffy squeaky toys up. He is only 7 months old and has only shown interest in tearing something up if it was already broken(had an existing rip or tear)This is only the 2nd or 3 toy he has torn up in his whole life(and he literally has at least 30 stuffy toys(some left by my sweet Bella--she passed away in March but most are brand new because when I saw he wasn't a Destructo-Dog, I went a bit overboard buyin him stuffies-So much that my Hubs was not happy with me but he was secretly glad I did it😈.)
See my review for the Jumbo Lambchop toy-That toy was and IS quite possibly the best stuffed squeaky toy available for bigger dogs. Only the MultiPet brand Jumbo tho-There are other brands that arent great. You can tell by the materials used on the face of the real Jumbo 24 inch ones from MultiPet. The Jumbo was a much better experience for us! I have also ordered the smaller one for him becuz he really wants the cat's lambie toy too. They have the 6 inch, not the "cat toy" version and they(and Ghost)love it. No one tears it up. I'll review it once his is delivered because while I know he doesnt rip the 6 inch one apart it is technically the cat's toy(not his) and we usually make him give it back to them pretty quickly. Ill review it when he gets his own & is allowed to do whatever he chooses. Hopefully he will treat it like Jumbo Lambie...Ok well, maybe not exactly that way cuz...Well, Lets just say he gets very, erhmm, frisky with his Jumbo Lambie. He doesnt like when we wash her but we do. Unfortunately he tries to take her outside in the dirt and/or in the pool with him. I will mention that more in my review for Jumbo Lambie. As for this standing up version-It MIGHT be fine for your dog or cat but it definitely was not durable for my Ghostie. It is a good size for a smaller/medium sized dog but definitely not good for puppies & especially those that still have their deciduous(milk/needle)teeth and not for even light to moderate chewers due to the material on the chest. That's what made Ghost tear his up. He nicked it with his teeth, a hole formed and that was apparently his cue to rip the squeaker out & tear the poor toy to shreds-He did have fun doing it tho. Haha. For some dogs this toy might be great fun.
It is definitely a great brand and the jumbo version is Ghost's fave toy of all time. Pricing on all of MultiPet's dog toys are amazing and I hope they stay that way! We keep several of the Jumbo Lambies here in case one "goes swimming" so we can wash it and he has one to carry/cuddle or in case one gets temporarily left behind somewhere cuz he wants to take it everywhere he goes. We let him bring her along except for on walks

Really durable
Color: Blue
Solid but not hard enough to break teeth. My dog likes this toy and won’t be chewing through it because it’s quite durable!
