I use silicone lube on condoms that I put over silicone toys and they have all stayed fine. The lube is on the outside of the condom. If you store your toys in upperware, make sure they are not touching each other. You can wrap them in cloth or plastic baggies or saran. They don't need to "breathe".

Many condoms use silicone lube. I have a Ridge Rider sleeve (TPR silicone) and Lelo Bo (TPE), both would come into contact with the silicone lube on the outside of the condom.

The EF materials guide says only use water-based lube with TPR silicone: link

It seems TPE toys can play well with silicone lubes: link

I probably won't buy unlubricated condoms just for this purpose, so I'll give silicone-lubed condoms a try with the Ridge Rider (TPR silicone) and see what happens - it's an inexpensive toy, so if the lube sticks to the toy, no big loss. Thankfully the Lelo Bo (much more expensive) should work with silicone-lubed condoms.

Somewhere on the forums you'll find the silicone toys vs. silicone lube debate

I've always wondered if it's okay to do as well but do it all the time myself.

I know the condoms I have are packed in silicone lube so it's both inside on the tip and outside. I've never had any problems on pure silicone toys but that's not to say that others won't.

I just got non-lubricated ones to put over my toys to avoid any "time of the month" potential staining of my most loved silicone toys. I figure if I need lube at all, I can just apply a water-based to the outside.

They even fit over the head of my Mystic Wand. It looks like its wearing a hazmat suit going into a nuclear situation, but it does the trick!
