unknown pico fuses--HELP!!

Hello all. Hopefully someone can help me identify these two fuses I have. I've been searching and searching all the different manufacturers and anything else I could, to try and identify these things. But to no avail. All I know is what they're marked with.
Both are axial pico fuses and both are yellow.

One is marked '102' on one side and then
K
C5 on the other side (the 'K' is above the 'C5').

Then the other is marked '104' on one side and then just an 'M' on the other...

The dimensions:
For the '102' one: from the body of the fuse to the end of the lead is ~28.5mm. The body of the fuse itself is ~4.3mm. Then the width of the fuse is ~2.6mm.

For the '104' one: body of fuse to end of lead is ~29mm. Body of fuse itself is ~3.4mm. And then the width is ~2.3mm.

These have been in our stock for who knows how long, so they could be obsolete? I have no clue.
Any help would be Much Appreciated!!
Danke

They may more likely be capacitors. The K is =-10% and M is +-20%. 104 is 10 and four zero's pF

Check them with an ohmmeter to see if they are fuses, resistors orpossibly capacitors. 104 could also be 100,000 ohms.
