For eight years, I always used elf ears made from Latex, some better, some worse, but for this season I got my first pair of silicone ears.
The difference is striking. they look so much better, are comfortable to wear and much more sturdy. The only downside is, I feel they are a tad too long, as I prefer ears with shorter tips. However, this is only MadhouseStudioFX second style of silicone ears, so I will keep an eye out for new releases.

They look great. Are they still in good order after these couple of months?
Also are they tip only or full ears?
They are still good. I wore them again in december, and I suspect they will hold a very long time. They are tip only, so I can still wear ear rings, but the edge is very thin so you see almost no seam, as you see in the photo.
