item texture has glitches [Solved]

[final cargo]

hello, i have created a mining tool
it works fine and all but i dont know why the texture is rendering like this
on the back side of the tool you can see it is hollow
and i also uploaded the texture itself
anyone knows why this happens?

and this is the texture itself

model file wooden_paxel.json

  "parent": "item/handheld",
  "textures": {
    "layer0": "mrm8hdis-collection:item/wooden_paxel"
  }
}```

your texture has a few 99% transperent pixels - highlighet with red

note: i missed atleased one while highlighting - so check all pixels

oh yes that was the problem thank you, and how did you find it out because i suspected this might be the problem but its almost invisible to the eye so i couldnt find it

i think i also had this issue once so i already suspected it
i then just checked the pixels via a color picker and well
