This belt was originally issued to troops stationed in Hong Kong. At that time, it was called 97 inner belt, 1999-2006 was distributed inland, and it was renamed 87 inner belt. The earliest style was CPLA, and the roller slide was straight with four teeth. In the later stage, PLA is a five-tooth curved slide. In addition, the pattern of CPLA model is different from PLA model.
Later customized models, mainly 352 1 and 35 14, are also good in workmanship, but not as heavy as the old models, with dark colors and lack of luster. PLA font backplane is not grainy matte texture, but the price is very cheap. I have also used a two-year replica version, which is better than most old models. Zhejiang Kunsack is the most difficult to use, but it is the thickest material, the heaviest weight and the brightest color among many manufacturers. The disadvantage is that the roller is too thick and not tight, and other lilies and patent numbers are easier to use.
