In December 2019, I was contacted by another collector about these pencils. They were announced on December 3 on a Delfonics Twitter post. Ten days later they were announced on the Delfonics website. Unfortunately, at this time, they seem to be sold out from the Delfonics website.
It took a couple of orders for him to get me a full set of these pencils, but I finally have a full set of these pencils.
Aside from the text printed on the side and the colors, these are standard P200 pencils. The cutout has the same information (PENTEL on line 1 and JAPAN and the mold mark on line 2), the inner body, clip, tip and cap are all the same.
500723 811 (P203) Light Gray
These pencils do not have a model number printed on them anywhere, so I am using the Delfonics part number from the stickers as the model of these pencils.
The color of this pencils is a light gray, with a medium gray text that just says the size (0.3mm) and DELFONICS.
The barcode for this item is 4516085307928.
500724 124 (P205) Neon Orange (Red)
This pencil is a bright orange with white text.
The barcode is 4516085307935.
500724 807 (P205) Dark Gray
This pencil is a dark gray color with white or light gray text.
The barcode is 4516085307959.
500724 811 (P205) Light Gray
This is the same light gray as the P203 above with the medium gray text.
The barcode is 4516085307942.
500725 807 (P207) Dark Gray
This pencil is the same color as one of the P205s above with the white or light gray text.
The barcode is 4516085307966.
500726 124 (P209) Neon Orange (Red)
Again, this pencil matches a P205 above in color, bright orange with white text.
The barcode is 4516085307973.
If you notice, the sequences of the Delfonics part numbers, the size is the first 6 numbers:
500723 = P203
500724 = P205
500725 = P207
500726 = P209
The last 3 numbers correspond to the colors:
124 = Neon Orange (Delfonics calls this Red)
807 = Dark Gray
811 = Light Gray
