Caliber Gourmet Brass Knuckles Cup - Black and Gold Ceramic Self-Defense Novelty Coffee Mug, Unique Knuckles Mug for Collectors, Perfect Odd Coffee Mug Gift Idea for Christmas, Father's Day & More

I love this product. I would buy it again. I have bought it twice because I accidentally broke the first one. The only thing I can say to other people that may be thinking about buying this is do not put it in the microwave. You can very easily burn yourself because of the coding that is placed on the brass knuckle portion of the mug aside from that this is an amazing product.

I'm a coffee cup fiend and this one is my favorite! It's so comfortable to hold and it's adorable

I purchased this for my husband. He enjoys using it

This is a very unique and nice looking mug. It appears to be of good quality, is easy to clean, and holds a fair amount of coffee. The finger holes in the knuckle portion are rather small though. If you have dainty hands, then it shouldn't be an issue. If you have big 'ol oven mitts like me, it might be a bit harder to hold onto.

Bummer about this but the holes were too small for my husband's fingers and it was a gift for him.

Very unique and nice quality

Excellent product. Gave as a gift. They love it

me llego en buen estado... solo un poco dañada la caja, ñero no me quejo... el producto estaba intacto, muchas gracias 9/10

Très bien

Je suis satisfait de cette achat malgré que la poignée pourrait etre plus grande pour permettre d'y insérer les doigts confortablement. (Fait pour de petites mains)

Un peu difficile à boire avec

Like the fact that it had the knuckle duster handle. However, I have regular sized man’s hands and my fingers barely fit through the holes I bought two of them as Christmas gifts for my son-in-law and my Son. I would be embarrassed to give these as a gift as I don’t think they would even get their fingers through the holes. As they are bigger men. And it looks to me like they would break fairly easily. As they are not a quality product.
