STANLEY, a hugely popular tool brand in America, presents these work gloves. This model was popular overseas, including in the US, but was never released in Japan and is now discontinued. In Japan, you're likely to only find thin work gloves or mechanic gloves. Importing from Amazon US to Japan would cost around 10,000 yen at the current exchange rate. The palm is reinforced with goatskin. The back of the hand is spandex. There are approximately 5mm thick rubber protectors along the index finger and thumb of both hands. The wrist has a Velcro closure with the logo. As the name suggests, these gloves protect your hands when using a hammer, but they would also be useful for outdoor activities and camping work.
