10 pcs VP Series Silicone Robotic Arm Vacuum Suction Cup,VP-R Single-Layer Vaccum Suction Cup Grip Device (VP8R)

These are TINY silicone flanged tubes (Vp4R) which are designed to pick up small parts when attached to a robotic arm that has vacuum activation. Sort of automated suction cups that can suck up a small item and then drop it when the vacuum is released. They are well made - no burrs or suffs - perfectly smooth and elastic. But, as you will see from the specs and from my picture, they are really TINY (small ones in pic - size VP4R - the larger are size VP6R). I was hoping to use them as an 'in ear' tube for my earbuds (I have really small ear canals!) - but these are too small diameter for my use. But they are well engineered for their intended purpose and are quite elastic and snap back to original shape when released. Sorry they didn't work for my 'off-label' use!
