The compact and lightweight brown 8-16x21 U-Series UP Binocular combines aspherical optical elements and BAK4 Porro prisms to deliver edge-to-edge image sharpness with a wide angle of view. The optical elements are also fully multicoated to provide a high transmission of light. With an 8-16x range of magnification and 21mm objectives, you obtain a wide zooming range and a compact form factor. You can easily spot your targets with a 5° angular field of view at 8x magnification and quickly zoom in on them with the optical zoom. To reduce image jitter at high zoom factors or for prolonged observations, you can connect the binocular to a tripod via an integrated 1/4"-20 socket. In addition to observing distant scenes, birds and game, the minimum focus of 9.9' allows you to study in detail close objects like animal footprints, marks or landscape features. The binocular also features a 2.6-1.3mm exit pupil range, a 14-11mm eye relief range, an interpupillary and a diopter adjustments.

The binocular is very compact, lightweight, and features a single piece frame that houses objectives, which allows for a synchronized interpupillary adjustment. To accommodate eye glasses wearers, the binocular offers sliding rubber eyecups. Also included are a carrying case, a neck strap, and eyepiece covers.

Dog approved.
Size: X-Large, Color: Cheese
I’m a 70 lbs Goldendoodle (supposed to be 65, don’t ask) and I love cheese. Real cheese. Sharp cheddar with sourdough bread is my dream, but apparently I’m “on a health journey,” so my people bought me this instead. Does this bone actually taste like cheese? No. I am not fooled. Do I still enjoy chewing it loudly while my humans are trying to watch TV? Absolutely yes. This bone satisfies my need to chew and my emotional desire for cheese-adjacent activities. It keeps me busy, saves the furniture, and lets me crunch dramatically during important dialogue scenes. The yellow color is nice — very cheese-coded — although some cheeses are white, so just something to consider for future versions. Also, good news: it doesn’t smell like cheese at all, which my humans seem very grateful for. Apparently they don’t want the carpet to smell like a deli. Weird. Final verdict: Not cheese. Still enjoyable. Would chew again. ~Barley

A Humorous Twist on Tough Dog Toys!
Size: Large, Color: Lobster 3 Pack
I recently purchased the Nylabone Power Chew Dog Toy Pack for Aggressive Chewers from Amazon, and I must say, these toys have been a hilarious hit with my furry friend. As a dog parent of a strong and determined chewer, finding toys that can withstand their chewing prowess is a top priority, and these toys deliver both durability and a touch of humor. The pack consists of three large/giant-sized toys in the shape of a lobster, cheese, and broccoli. The unique and amusing design puts a smile on my face every time I see my dog interacting with them. The unexpected twist brings a playful element to our daily playtime sessions, making it a fun and engaging experience for both of us. When it comes to durability, these toys excel. My dog can be quite aggressive with their chewing, and I've struggled to find toys that can withstand their powerful jaws. However, the Nylabone Power Chew toys have proven to be impressively tough and durable. Despite rigorous chew sessions, these toys have remained intact, with no signs of wear or damage. They provide a reliable outlet for my dog's chewing instincts without the risk of shredding or ingesting any harmful materials. The textured surfaces of these toys add an extra layer of interest for my dog. The ridges and raised bumps provide sensory stimulation, promoting healthy oral hygiene and helping to clean teeth and gums as they chew. I appreciate the added dental benefits these toys offer, as it helps maintain my dog's dental health while they engage in play. I also appreciate the size options available in this pack. Large and giant-sized dogs often require bigger toys to accommodate their larger mouths and chewing strength. The included toys are appropriately sized for larger breeds, ensuring a comfortable grip and maximum enjoyment during play sessions. As a bonus, these toys are made from high-quality, non-toxic materials, so I have peace of mind knowing that my dog can safely interact with them. Safety is a top priority for me, and Nylabone consistently delivers in that regard. In conclusion, if you have an aggressive chewer and are in search of durable, funny, and engaging dog toys, the Nylabone Power Chew Dog Toy Pack is a fantastic choice. These toys provide hours of entertaining play, withstand even the most determined chewers, and offer dental benefits. Embrace the humorous twist and enjoy watching your furry friend engage in safe and engaging play with these fantastic toys. Invest in the Nylabone Power Chew Dog Toy Pack today and let the lobsters, cheese, and broccoli bring laughter and durability to your dog's playtime!

Shark dog approved
Size: Large, Color: Broccoli, Size: Large, Color: Broccoli
My new baby shark.... I mean puppy really enjoys chewing. I can't just give her a ton of pig ears or bully sticks all day, which she would definitely love, so I'm constantly looking for well made chew toys. I'd put this right up with Kong. Very durable and nice. I also love the different textures, she seems to also love it. She can gnaw at the top and chew on the stem. She wanted it as soon as I opened it - it does smell like bacon but I haven't taken a chomp at it to be able to write a complete review! My dog is about 23 lbs but I can see a 80 lb dog chew this, it's not small.

So cute
Size: Large, Color: Pumpkin
My French Bulldogs have really strong jaws and are aggressive chewers. These really are sturdy and last a good amount of time. They are a bit heavy and awkward for my dogs to hold onto but they do like them.
