What the allowance actually buys
One allowance here buys 534,960 EXP, the best on the Lv 56 Leatherworker tradecraft rung — matched exactly by 1 other leve of the 3 there, with the rest trailing at 127,600 EXP or less.
On whether to wait: the best Lv 58 Leatherworker tradecraft leve returns 593,380 EXP per allowance, 11% more than the best on this rung, while the Lv 54 rung behind tops out at 560,140 EXP.
At Lv 56 this data holds 54 leves paying EXP across 3 categories: the 24 Tradecraft ones average 390,755 EXP per allowance, the 3 Fieldcraft ones 1,032,386 EXP and the 27 Grand Company ones 195,640 EXP, which puts this leve 37% above its own category's average.
Dragonskin Wristbands ×1 is a Lv 58 Leatherworker recipe, 3 steps deep through 5 intermediates, costing 26 units of raw material and 47 crystals.
Handing that in returns 20,575 EXP and 43 gil for every unit of raw material the order swallows, and the tree needs Goldsmith and Leatherworker.
