Size: 9" across, 8" from front to back, 4.5" tall
These come in a set of 2 for the price listed.
These are actually made out of hollow foam, so that they can easily fit over whatever base is made for them, unlike our realistic hooves that are more thick and solid.
These are extremely lightweight since they are hollow, and are basically a shell; so you would fill them in with foam or something to keep them from getting dented and what-not. You can also cover them with fleece or fur if you'd prefer. You'll need to scratch up the inside of the hoof where it's smooth in order to glue it down; use an industrial glue (like shoe goop or E6000) and then use weight and wait overnight for the glue to fully set.
Just keep in mind that foam -will- yellow with UV exposure over time, so lighter colors (like white or bone) could yellow over time, much like upholstery foams. So those are best covered. If you choose to get a colored version and don't want to cover them, there will be a color swirling effect due to the matte finish. It's also not unheard of for there to be some small bubbles here and there on the surface.
