THETCHRY Plastic Cutting Board Set of 3: problems, parts and running costs

Checked: 2026-10-19

Summary

The THETCHRY set is three BPA-free plastic boards — 15 x 10 in, 11 x 8 in and 9 x 6 in — that are reversible, dishwasher-safe per the listing and sold almost entirely through a single marketplace storefront. There is no independent test and no findable owner discussion of this exact set, so the practical risks are the class-level ones for budget plastic: knife scoring, dishwasher warping and stain or odor retention. Running costs are just water, detergent and eventual replacement; resellers list the set at about $15.93 (October 2026), so a two-year replacement cycle averages $7.97 a year.

Common problems and fixes

Deep knife scarring — independent testing of other plastic boards found noticeable scoring on every board tested, and USDA says to discard a board once excessive wear or hard-to-clean grooves develop; there is no THETCHRY-specific figure for how fast this set scores. [7][8]
Dishwasher warping — Wirecutter warns plastic boards can warp on delicate or eco cycles; remove the boards before the dry cycle and use a gentler setting. No controlled dishwasher-cycle test exists for this set. [10]
Staining and odor retention — Food Network’s plastic-board testing checks odor retention after garlic and onion and stains from beets and turmeric in light-colored plastic; wash the boards promptly and expect marks on light colors. [11]

Parts and consumables

Whole replacement set — eBay resellers list the three-piece set at about $15.93 (October 2026); replace when scoring makes the surface hard to clean. [4][5]
Oil, conditioning wax, blades or filters — not applicable; THETCHRY’s oil advice is for its wooden boards, not this plastic set. [1]

There are no scheduled consumables: no filters, oil or subscriptions.

Yearly running cost

The set uses no electricity, motor, filter, disposable pads or subscription, so the running cost is household water and detergent plus eventual replacement. Using the checked $15.93 set price, replacing the whole set every year costs $15.93 a year, every two years averages $7.97 a year and every three years averages $5.31 a year. Those are condition-based scenarios, not a durability claim.

When it is a good buy

eBay resellers listed the green three-piece set at $15.93 (October 2026), and a checked cluster of live reseller prices sits near $16. Under about $12 the set is a reasonable default for three color- and size-coded boards; $12-16 is fair; above about $16 tested brands are available for little more. The clearest like-for-like alternative is the Freshware BC-300PK, listed direct by its manufacturer for $13.99 (October 2026) with documented 0.3-inch thickness and juice grooves; the OXO Good Grips two-piece set is $27.99 and has published independent testing, though it offers only two boards.
