Bordered Concrete Texture Pack !
This texture pack was made to make messing around with redstone circuitry easier.

Details
This is a 16x16 texture pack. All I did was to extract the textures from the Minecraft folder and add a 1 pixel thick black border with 20% opacity.

Compatibiliy
This texture pack will work fine in the 1.16 version of Java Edition Minecraft.

Note
When you try to open the texture pack in version 1.17 or above, you may get an incompatibility message. But just press "OK" and continue playing, the texture pack will work just fine.
