update content : The picture shows the com`parision to GMK and SP SA，Overall, we see that this height is closer to the GMK，but the globoidal surface still retains the original design of the spherical caps.

Hello everyone，I am Budda from JTK.

The difficult birth process of JTK HSA keycaps：

• 2016-09--------Designing drawings
• 2016-11--------Start moulding
  
• 2017-04--------In the first test, there were many problems and a lot of modifications.
  
• 2017-08--------In the second test, most legends were not a problem. Because of the high requirement of bright doubleshot, the difficulty is very great. Some keycaps with Multi-legends had poor effect (about 10), so the first time we redo the mould.
• 2018-05--------In the third mold test, one year later, the main reason was JTK factory had too much work to do, so we delayed. Multi-legends still did not work well。
• 2018-08--------In the Fourth test, Multi-legends keycaps effect was still not good, the second re-made die
• 2019-05--------In the fifth test wefound that the root cause of the poor font (there was no need to redo the mould before, wasting a lot of money and time), and the modification was completed.。
• 2019-07--------Re-amendment all the bottoms and do all final hand polishing the moudls to make the products better
