What is the opinion of Reddit about the
MITUHAKI 104 Key Profile Printed Translucent Blank Top All Light-transmitting Keycaps – (104 Key)1 104 Key OEM Profile Side Printed Translucent Top All Lig – Keyboards & Mouse Keycaps & Switches?

They are a mixed bunch but i’m assuming you’re talking about the ones on the letters. Those are blank top keycaps. I forget exactly where I got them from but they are the same ones shown in this amazon listing.

You should be able to get a better price from another source as I don’t remember paying that much for these.
