It is not our count and we do not adjust it.
It is the sort of detail that only matters once, and only if it is wrong. Every listing on this site carries the figure the supplier gave us for exactly this reason.
Where the number comes from
Assorted packs are the category where expectations slip most often. Four points settle it.
Every set is listed with the piece count printed on its own packaging — if the pack says 320 pieces, the page says 320 pieces, and if it says nothing we leave the field empty.
What to measure at your end
Before ordering washi tape sets, take the measurement the product page uses and compare like for like. Where our page is silent on a figure, the supplier did not give it, and we would rather leave the line blank than fill it with an estimate.
If it still does not fit
Tell us within the return window and we will sort it out. A change of mind is a customer-paid return; a wrong item sent by us is ours to pay for. Both are on the return policy page in full.
