Go to AmazonWe are not ready to call this price.
We check at least every 12 hours and hold a day-by-day record of what this cost: 3 days of it so far. Calling a price high or low needs 7 of those days and at least one change, because a range needs two prices: this one has not moved since we started watching. If it is still $39.99 on October 27, this box will say so: a price that has held for 10 days is an answer too.
1 kg of TPU: $39.99 a kilogram at today’s $39.99. Every spool, per kilogram
