Jeff from the United States saw our products on Alibaba. He was very interested, so he sent us an inquiry and wanted to consult the long-handled test tube brush kit. He said customers complained to them that the handle of the test tube brush kit was too short to control and difficult to clean.

We asked Jeff about the size of the test tube brush kit they had previously purchased, and we suggested that they could lengthen the stainless-steel handle or attach a handle. The price of installing the handle will be more expensive than the lengthened stainless steel because of the increased cost, but the control and feel of the handle are relatively better than stainless steel. Jeff wanted to compare the difference between the two long-handled test tube brush kits, so we proofed the two long-handled test tube brush kits.

Two weeks later, Jeff received the two long-handled test tube brush kits we sent in the past. After comparison, Jeff reported that he prefers the test tube brush kit with a wooden handle, because it feels better and is suitable for them. After a week of negotiations, we finalized the cooperation with Jeff and customized 5,000 test tube brush kits for them with wooden handles.
