Switch from PVC to a Natural Rubber Suction Cup
If you prefer Natural Rubber to PVC we now have an upgrade option for you.
This 60mm natural rubber suction cup is solid and strong and once it suctions will hold super tight. It cannot be described as delicate, but it does its job very well.
It is best suited to glass, stainless steel and shower acrylic - because it may leave a mark on release (which you can remove with cream cleanser). It would pay to release and re-suck regularly to care for the surface beneath. Do not use this super strong sucker on a more delicate surface. Your Block Dock will stick a little further out from the wall than with pvc, and the black colour is definitely more noticeable. It's the best option we can find for #plasticfree.
This suction cup has a different shaped head to the pvc. Use a slide and twist motion to get it through the Block Dock's keyhole. Then wet its back and place where you want it - push very firmly on the suction cup's flat head toward the wall. Once it's attached, if you want, rock the Block Dock downward until the flat head is near the top of the keyhole. A bit of lather will help with the movement. It works perfectly fine sitting lower also. When you want to remove it from the surface, just pull the wee tab on the suction cup or pick at the edge and break the suction. To remove the suction cup from the Block Dock you'll find it easily pops out from the top of the round part of the keyhole when you you use a peeling motion with your thumb. The trick is to relax while you do it!
If natural rubber is your preference instead of the pvc, simply add the option called SUBSTITUTE (it's selected when there is no line around it) and the number you need for your order and we'll send them INSTEAD of pvc. If you want natural rubber suction cups as an item on their own in addition to pvc, choose the option called ADDITIONAL.
These suction cups are made in Shanghai from 100% natural rubber.
