Very nice end caps
These end caps are being used to cover solar light support tubes for the winter. Did not want to leave the lights out for the winter. The OD of the tubes were 25mm; the ID of the end caps are 25mm. The caps installed very easy. Appear to be of good quality but time will tell. I would purchase again.

Serves a purpose!
We have a puppy who enjoys chewing the ends of our black drawer pulls. We have tried the bitter spray, and covering them with tape…but nothing works. She has managed to chew off the black paint surface, so the silver shows through. Ugly! So, I measured the diameter and ordered these. She still chews the ends of the pulls and has done some damage to the caps, but they remain on! They don’t slip off easily and are generally protecting the surface. I like that there are a lot of the caps, because we will need to replace them often. I am pleased with the product.

Just as good as new bongó caps
I have a makeshift solution. I put the 5mm caps over my bongó bolts (a little too tight.) Then placed the 8mm caps over the 5mm. This is still smaller and softer the the original caps but probably more reliable and much cheaper than nearly $20 for original 8 caps thst often fall off

Does exactly what it promises—caps off screws securely. Helps prevent snags and accidental cuts. Works on similar items too. Simple and effective,
