They do not have the Triangle Ric ones, but have a few block options. They are cheap, they are easy to install and remove.
I have installed them on two of my basses and removed them from one without issues (Both Rosewood) I do however recommend you use masking or paper (artist) tape when installing the block inlays because they can be a little tricky to line up correctly. (I did not do this the first time as you can see in the photo)
also buy two sets just in case you screw up (like I did), at $7.00 a set it is worth it.
Here is a photo of my FSR MIM Jazz with block inlay Stickers
