I had assumed that these switch toppers would be flexible, and somewhat rubbery. Instead, they are made from hard, inflexible plastic. This is not a problem, since they appear to be very durable. Fit depends on your equipment. I would expect them to be a good fit on most American boutique effects pedals. I can confirm that they fit the USA-made stomp switches on my Barber LTD SR overdrive, Bad Cat Siamese Drive, and Line 6 HX Stomp. As I had hoped, the translucent white tops pick up the colour from the LED switch surrounds on the HX Stomp. However, my GFI Specular Tempus delay/reverb and Zoom G5n both have odd-sized switches. These toppers are too large for the undersized buttons on the GFI, and too small for the large ones on the Zoom.
