T4/33 → This is a wig or hair extension color blend code.

T means "tipped" or "two-tone" (the top/root is one color, the ends are another).

4 is a dark brown base.

33 is a dark auburn/reddish brown.

So T4/33 usually means dark brown roots fading into a rich auburn tone.

Color straight → The hair texture is straight.

Bon → Likely shorthand for "bonnet" or "bonded" (depending on the product), or it could mean "bun" if it’s a hairpiece style. In wig listings, it might also refer to the "cap construction" (like a bonnet cap).
