Is this wig really glueless?

Yes. It is built for a glueless install, so it relies on the cap's fit and any straps or combs rather than adhesive. That makes it easier to take off daily, but the hold depends on how well the cap fits your head.

What does 13x4 HD lace mean?

The 13x4 closure gives 13 inches of lace across the hairline and 4 inches back, so you get a deep parting area. HD lace is thin and blends with the scalp, but it is delicate and needs gentle handling.

Can I heat style or color it?

It is human hair, so it can be heat styled and colored. Use moderate heat and a heat protectant, and have a professional color it if you are unsure, since repeated processing weakens the hair.

How do I keep the body wave from tangling?

Detangle gently from the ends up, keep the hair moisturized, and wash it in loose sections. Sleeping on satin or silk helps, and brushing dry hair roughly is the main cause of tangling and shedding.

Is it ready to wear out of the box?

The hairline is pre-plucked, which saves plucking work. You may still want to customize the lace, trim it to your hairline, and style the wave before wearing it.
