Love these molds! They are great quality and easy to useI feel like the small one is too small. It would be fine for a newborn kitten…. and the big one is fine.Me gusta tener las dos opciones de un huesito más grande y uno más pequeño para mi funcionan bienI highly recommend this item. Worked just as described. Sizes are perfect. Worth to buy!Great for making resin dog tags. Easy to use. The resin came right out when it was dry. The only thing I didn’t like was that the larger mold was bigger than I expected. It might have said the size in the description and I didn’t see it, but I think the smaller one was a perfect size.So they are great but if you use them for an actual animal to use you need to make some supports so that the ring won't break off the top. I would use some small guage wire or a thin jumpring and imbed it I'm your resin. I bought it to make an embellishment for a pet memorial frame so I didn't have to worry about it.Like-sizeDislike-nothingLove them. My only complaint is no one sells this pattern in a mold that is several on one piece. But like them. Great priceYo lo uso para hacer collares de perros y se ve bueno, no lo he usado pero desde mi punto de vista es bueno, buen grosor y me gusta el tamaño, lo recomiendoBien por la calidad del molde pero un poco delgado para poner la argolla para las placas y debido al tamaño no caben en ocaciones los nombres de las mascotsSon de silicon pero se sienten como si fueran de gomita, no es tal cual silicon del rigido, los tamaños son adecuados para la placa de perro, ahora si que el que te guste de los dos tamaños le haces a tu mascota. Tardo 15 dias en llegar a Veracruz puerto, viene de china.Súper buena calidad y las medidas son exactas a las que están marcadas.Súper bien ?
