Looking for filter housing

I am looking for a place to buy filter housings for standard 1.25"
eyepieces. I have 2 .98" diameter filters, but no way to mount them. The
cheap color and moon filters I have are too bulky and the filters won't fit
in them. Based on on-line pics there are slim filter housings. Does anyone
know where I can get some?

Thanks,
