10 Piece Suction Cup Replacement Set with Plastic Grommets

I bought the DIY window shade that uses these very suction cups. They work really well -- we live on a boat and need something that keeps out the heat while fast to put up or take down. But after a couple of years the cups flatten, getting little or no suction to the windows. So you'll need these to replace thelm.

Over a year ago I bought the front cab window coverings you offer made specifically for my Class B on a Ram Promaster chassis. I loved how quickly they installed with the suction cups. Now it's time to make my own coverings for the other windows and am pleased you sell these suction cups/grommet combinations as I plan to use them to secure my covers to the windows. I've made a prototype, and they work perfectly. Great product. Thanks.
