To offer this at a low price, I have chosen to ship via standard mail (non-standard size mail). There is no tracking service or insurance. Also, it seems to take a bit longer for delivery. On several occasions, it has taken about a week. This was made from cedar wood approximately 10mm thick. It is item Ⓓ in photos 6 and 7. It has a 4cm slit only. You can check if a Yu-Packet Post package can be shipped simply by passing it through the slit. I created this to be able to offer it at a low price, so that as many people as possible can use it. The frame material has been made thinner. There are no issues with precision or strength. Thanks to over 1,000 customers, I am now able to create better products at lower prices. I feel it has become lighter and perhaps even easier to use. I also offer a thicker board made of popular cypress wood. If you desire a more durable item, please purchase that one. The photos are for size and shape reference. The item you receive will be of equivalent quality. This is an item I created out of necessity as a Mercari user, something I wished I had. I am confident you will be satisfied with this product. Wood is flexible, strong, polishes with use, and is kind to nature. Above all, the texture of wood is superb. I have received many comments expressing surprise at how durable and pleasant to the touch the item is. I have been using it myself for many years. I will be using recycled materials for packaging. Also, with standard mail, the shipping cost changes based on even slight weight differences. It will be packed with thin paper. Please understand. If you purchase multiple items and they can be shipped together, I will offer a discount equivalent to the shipping cost. #TakawataHandmade #TakawataPackingScale #YuPacketPost4cm #YuPacketPost #ThicknessMeasuringRuler #ThicknessGauge #ThicknessMeasuringItem #ThicknessMeasuringGoods Yu-Packet Post Thickness Gauge 4cm Thickness Measurement Ruler Scale Yu-Packet Plus Measuring Ruler Mercari Shipping Mercari Scale Shipping Ruler Thickness Measuring Ruler Thickness Measuring Item Thickness Measuring Goods Thickness Measurement Scale
