<p>1mm version is approved</p>

<p>so now customer is requesting 1.3mm version</p>

<p>and a new version for 1.6mm (a bit wider ring)</p>

<p>Fon, this one is new model, so should we enter new order and to be done as homework? or we keep same order (better) and you&#39;ll manage to keep track and tell me later?</p>
