Thank you for viewing. These are adjustment spacers primarily used on construction sites. * Red → 5mm, 50 pieces * Black → 3mm, 200 pieces * Black → 1mm, 100 pieces All sizes are: 70mm x 45mm They are convenient for level and height adjustments of base metal fittings, such as those used by sash installers. They can also be used for various other purposes. * Although they are new and unused, they are surplus items from the construction site, so the plastic bags are dirty. The contents are new. (They have not been opened.) ※ Due to various circumstances, we may change the color of the product at our discretion. Please understand. * 5mm Black ↔ Red * 3mm Black ↔ Yellow * 1mm Black ↔ Blue * As a private seller, I do not issue receipts. * I am also selling on other sites, so I may delete the listing without notice. Please purchase if you understand the above. If you are concerned about the quality or are a perfectionist, please consider carefully to avoid any problems. Thank you for viewing.
