This is a small-lot set of 10 thermal roll paper cores for receipts, plus 2 bonus short receipt cores. Many other listings offer large quantities, so this is for those who want a smaller amount. Thermal Roll Paper Cores: Length: Approximately 9.8cm Width: Approximately 3.3cm Receipt Cores: Length: Approximately 5.4cm Width: Approximately 3cm For those who enjoy crafts and DIY projects. Great for kids too! If there's good demand, there will be irregular listings in the future. *If you wish to purchase this set along with another set* Due to shipping costs, there are no combined discounts even if you purchase them together, so please purchase each item separately.
