Introducing a full-metal addition to the continually evolving 2100 style of timepieces that inherit the legacy of the first-ever G-SHOCK, the DW-5000C. Luxe full-metal construction with a screw-back case, bezel, and band crafted in stainless steel creates a streamlined, minimalist design, while protecting the module from impact when dropped. High-density mounting keeps the analog-digital combination module slim, while still providing the advanced functions you love in a compact profile and comfortable fit. We take it way back with the octagonal bezel and dimpled band design of the original from 1983, all done in metal. The stainless-steel bezel — formed three-dimensionally through a time-consuming forging, cutting, and polishing process — is finished beautifully with a circular hairline treatment on the top surface and mirror polish on the slopes. Buffering components made of fine resin are installed between the bezel and the case for a shock-resistant structure with a full-metal exterior. The dial’s delicate molding, achieved with fine processing technology from Yamagata Casio, is paired with indexes with a silver-color vapor deposition finish for an eye-catching design and even easier read. Pairs with a smartphone via Bluetooth®. Simply tap into the dedicated app for precision timekeeping that keeps you on track. With Tough Solar, a high-brightness LED light, and a range of other convenient functions, this is a timepiece that delivers on style and practical utility.

Happy puppy with this durable bone
Size: X-Small, Color: Pink
Our new puppy loves the texture and thickness of this bone. She is an aggressive chewed and has not yet destroyed this bone. We have purchased Nylabones for our dogs year after year and have had several happy puppies over the years.

Amazing for Heavy Chewers!
Flavor Name: REAL Jack Salmon, Size: Puppy (2-Pack)
If you have a dog that destroys every toy in minutes, Benebone is a total game changer. These chews are incredibly durable and actually last—especially for strong or aggressive chewers. They’re made with real flavors like bacon, chicken, and peanut butter, which dogs absolutely love, and you can tell because they keep coming back to it again and again. What I love most is that they keep my dog busy and satisfied without the mess or smell of traditional bones. They’re also thoughtfully designed with shapes that are easy for dogs to grip and chew comfortably. That said, like any hard chew, it’s important to supervise and replace it if it gets worn down—but overall, this is one of the best long-lasting chew toys out there. Highly recommend for anyone with a serious chewer—worth every penny! 💛🐶💛

Excellent quality chews. Tiny Puppy size is perfect for adult toy breed dogs.
Flavor Name: REAL Bacon, Size: Puppy (2-Pack)
I bought the Tiny Puppy Bacon flavor 2-pack package of these, and my dog and his sister are obsessed with them. They chew on them multiple times every day. They seem to be fairly durable, although I expect they will break down over time, which is okay as it’s a chew. I like that they stay intact, with no chunks breaking off for the dogs to swallow. The dogs do ingest a small amount as the material breaks down, but I always supervise them when they have these, and there haven’t been any problems. It’s difficult to find good chews for toy breed dogs like our 12-pound Shih Tzus, so I was happy to find these. They are pricey, but I believe they are worth it. The dogs love to carry them around, and my little guy even plays with his chew sometimes like it’s a toy.

Durable, engaging, and dog approved
Flavor Name: REAL Bacon/REAL Maplewood, Size: Puppy Tiny (2-Pack)
These chew toys are great for keeping dogs entertained and engaged, especially for gentle chewers. The quality feels strong and they hold up well compared to many other toys. The real bacon scent keeps dogs interested and coming back to them often. I’ve ordered multiple packs over time for my own dogs and even gifted them to others because they’re so well liked.

The "Y" is a staple! The other is useless.
Flavor Name: REAL Bacon, Size: Small – 2 Pack
Leaving a 4-star review because she has chewed this "Y-shaped" Benebone almost down to the nubbins. At first she didn't want much to do with it, but something clicked and once she started chewing it, it's become a staple in her chewing repertoire. But the other shape... the double-pull with the lines on it... is apparently not chewable for her. She'll tote it around, but won't really sink her teeth into that one. She's still a puppy, so maybe she'll start on the double-pull shaped one later. But we'll probably hafta get a larger Y-shape in a month or two... that one's totally worth it!
