The ToyGem insert kit listing, bullet by bullet

Five bullets: 450 brass threaded inserts in 15 sizes from M2×2×3.2 to M8×10×10, each counted; use in PLA, PETG, ABS and other thermoplastics; seven insert tips for M2 to M8 and two adapters; a 60 W iron heating quickly, with a dial from 200 to 450 °C; and a complete kit with tweezers, a stand and a storage box.

ToyGem’s tips are for inserts

Melting threads into plastic. An insert tip holds a brass insert and presses it into a printed hole as the plastic softens. These tips are not for soldering joints, and the listing does not present them that way.

ToyGem’s counts

From 50 M2 inserts down to 5 of the largest M8, the first bullet gives the quantity for each of the 15 sizes. No bullet suggests an iron temperature for pressing them into PLA or PETG.
